Description

[Technical field]

[0001] The present invention relates to a method for producing transparent ash powder crystals using only ash components derived from a single individual by utilizing phosphoric acid extracted from cremated remains as a catalyst in the ash powder heat treatment process, and by adjusting the classification ratio of raw ash powder and phosphorus-extracted ash powder, the transparency of the ash powder crystals can be adjusted by adjusting the phosphorus content in the crystals using only the remains of a single individual, thereby satisfying the aesthetic demands of consumers and making it easy to use in various types of jewelry. [Background technology]

[0002] Burial has traditionally been the main method of placing bodies in Korea, but each grave occupies an average of 15 square meters, and according to statistics, in Korea, an area equivalent to half the size of Jeju Island is used as a cemetery. In addition, graves are generally located in remote areas or in mountains, making their management very difficult. This burial custom is discouraged because it does not fit the Korean situation, where available space is small and land values ​​are constantly increasing, and because modern society has become generally Westernized and nuclearized, and social perceptions of funeral customs have changed significantly. Cremation is gradually replacing it. Meanwhile, with the development of a culture of raising companion animals, the number of cases where companion animals are cremated and funerals are held just like humans is steadily increasing.

[0003] Meanwhile, the remains remaining after cremation are generally crushed into powdered bones and placed in an ossuary, and then stored in an open-air ossuary constructed of an ossuary or stone structure. In this case, the remains form a porous structure with many micro-cavities developed as a result of burning at high temperatures, and have very strong adsorption properties. Therefore, there is a problem that the remains are degenerated and decayed, producing a foul odor, and the remains are damaged by the intrusion of pests, as they are strongly absorbed or adsorbed by moisture, foreign matter, bacteria, etc. from the surrounding environment during storage.

[0004] To solve these problems, a technique has been proposed to turn bone powder into a mortuary or gemstone so that bone powder of a deceased person or a deceased companion animal can be stored by processing bone powder to increase its stability and at the same time adding aesthetic value and storability. However, in the case of conventional bone powder mortuary processes, gas direct flame or plasma methods are generally used. In these methods, gravel-like mortuary is produced by utilizing the characteristics of the bone powder being acidified when melted at high temperatures of 1,800 to 2,200 degrees Celsius and the characteristics of a high melting point quenching body. However, in such cases, not only is there the inevitable loss of bone powder due to oxidation caused by the direct flame method and volatilization caused by the high temperature process, but there is also a high possibility of deterioration even after mortuary production. In addition, in the case of conventional gemstone production techniques, a process has been proposed in which only specific elements in bone powder are extracted and mixed with ruby ​​or sapphire to synthesize them, or carbon is extracted to produce artificial diamonds. However, even if this technology maintains aesthetic functionality in appearance, it uses only a small portion of the elements compared to the entire bone powder as raw materials, which is quite different from the same funeral culture that places importance on preserving the bones, and ultimately the problem arose that the fundamental purpose of the technology in question could not be achieved.

[0005] <Patent Documents> Korean Patent No. 10-1516149 (published on May 4, 2015) "Burner-type bone powder molding device" An apparatus for heat-treating remains powder to produce ball-shaped crystals, and a method for producing crystals using this apparatus have been disclosed; however, there is a problem in that heat-treating remains powder at high temperatures of 1,800°C or higher may result in the remains powder disappearing due to volatilization.

[0006] <Patent Documents> Korean Patent Publication No. 10-2013-0082462 (published on July 19, 2013) "Method for storing cremated remains crystals mixed with charcoal composition" A method for producing crystalline remains that has excellent antiseptic, deodorizing and antibacterial properties has been disclosed, but there is a problem in that the content of bone powder in the crystalline remains is low because a considerable amount of substances such as charcoal, ceramics, seven precious stones and tourmaline are added during the manufacturing process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The method for producing ashes powder crystallization according to the present invention will be described in detail below with reference to the accompanying drawings. Unless otherwise defined, all terms in this specification have the same general meaning as understood by a skilled artisan in the technical field to which the present invention belongs, and if there is a conflict with the meaning of the term used in this specification, the definition used in this specification shall be followed. In addition, detailed description of known functions and configurations that may unnecessarily disturb the gist of the present invention will be omitted.

[0024] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification can be used in a commonly understood sense by those having ordinary skill in the art to which the present invention belongs. Furthermore, commonly used terms defined in dictionaries are not interpreted ideally or excessively unless explicitly defined otherwise. Throughout the specification, when a part is described as "comprising" a certain component, this means that it may further include other components, not excluding other components, unless otherwise specified to the contrary.

[0025] Meanwhile, bone meal is generally a term used to refer to a substance obtained by pulverizing the bone components remaining in the corpses of vertebrate animals, but in this specification, the term "bone meal" is preferably understood to mean a substance obtained by pulverizing the bone components remaining after cremation of a deceased person, or a dead companion animal or livestock.

[0026] The manufacturing method of the ashes powder crystal according to one embodiment of the present invention will be described with reference to FIG. 1. The manufacturing method of the ashes powder crystal according to one embodiment of the present invention includes a mixing step (S11) of mixing the ashes powder with a catalyst agent to form a mixture, a drying step (S12) of drying the mixture to form a dried material, a dividing step (S13) of pulverizing the dried material to form a pulverized material, a heat treatment step (S14) of melting the pulverized material through a heat treatment process to form a molten material, and a crystallization step (S15) of cooling the molten material to form a crystal.

[0027] The mixing step (S11) refers to a step of uniformly mixing the ashes powder with a catalyst to form a mixture, and the mixing method for forming the mixture can be applied without any particular limitations, for example, it can be easily mixed manually in addition to known mechanical mixing methods such as ball mills, cutter mills, automatic mortars, bead mills, jet mills, and flat mills. In order to form a purer mixture, it is preferable to mix using a mixing tool made of a chemically resistant material such as quartz or Pyrex (registered trademark), but it is not necessarily limited thereto.

[0028] The catalyst may be any material that can form a eutectic point lower than the melting temperature of the ashes when mixed with the ashes powder, and is preferably a silicon compound, a boron compound, a phosphorus compound, or a mixture thereof. More preferably, the catalyst is a phosphorus compound selected from one or more of the group consisting of metaphosphoric acid (HPO3), pyrophosphoric acid (H4P2O7), phosphoric acid (H3PO4), phosphate compounds thereof, phosphorus pentoxide (P2O5), or a mixture thereof. More preferably, the catalyst is phosphoric acid (H3PO4). The phosphoric acid can act as a flux that lowers the eutectic point during the ashes powder melting process, and can also play a close role in forming crystals by activating phosphorus in the ashes powder using its property of crystallization when its concentration is high, and can also play a role in preventing the loss of ashes powder due to volatilization caused by high temperature conditions, which is one of the main problems that occur during the melting process. In addition, the transparency of the crystals finally produced can be adjusted according to the phosphorus content in the ashes powder.

[0029] In the mixing step (S11), the catalyst agent is phosphoric acid as described above, and the catalyst agent is preferably phosphoric acid as an 85% aqueous solution, and is mixed at 100 to 200 parts by weight with respect to 100 parts by weight of the ashes powder. Preferably, the catalyst agent is mixed at 100 to 180 parts by weight with respect to 100 parts by weight of the ashes powder, and more preferably, the catalyst agent is mixed at 160 parts by weight with respect to 100 parts by weight of the ashes powder. If the catalyst agent is mixed at 100 parts by weight or less with respect to 100 parts by weight of the ashes powder, the ashes powder does not melt sufficiently, and a problem occurs in that no crystals are formed. If the catalyst agent is mixed at 200 parts by weight or more, the excessive phosphorus content causes the melt to erupt outside the melting mold during the subsequent heat treatment process, or the releasability from the melting mold after crystallization is not ensured, and the shape of the finally obtained crystals is different from the normal shape and has a flat shape, which reduces the aesthetic functionality. Meanwhile, in the mixing step (S11), in order to facilitate the reaction between the ashes powder and the catalyst, 20 to 60 parts by weight of distilled water may be added to 100 parts by weight of the ashes powder.

[0030] In the drying step (S12), the homogeneous mixture formed in the mixing step (S11) is dried under high temperature conditions, preferably at a temperature of 300 to 600° C. to form a dried product, and it is preferable to perform drying by appropriately setting the drying temperature or drying time depending on the amount and state of the mixture, etc. If the drying is performed insufficiently or excessively, it may affect the shape and transparency of the crystals to be produced later.

[0031] In the dividing step (S13), the dried material formed in the drying step (S12) is pulverized to form a pulverized material. The dried material after the drying step (S12) is in a solidified form like cement, and must be divided into small sized pulverized materials in order to melt it. As the pulverization method used in the dividing step (S13), various known pulverization methods can be used, but it is preferable to use one or more methods selected from a disk mill, a ball mill, and a cutter mill in order to minimize the loss of the pulverized material due to the pulverization. The size of the pulverized material formed is preferably 80 to 120 mesh, and more preferably 100 mesh.

[0032] In the heat treatment step (S14), the pulverized material formed in the dividing step (S13) is melted through a heat treatment process to form a melt. In the heat treatment process, the pulverized material is placed in a prepared melting mold, and then the pulverized material is melted through a heat treatment. Since the shape of the manufactured crystal varies depending on the shape of the melting mold, the shape of the melting mold can be arbitrarily selected according to the shape of the crystal to be manufactured. The material of the melting mold is preferably a ceramic material characterized by being one or more selected from the group consisting of alumina, zirconia, mullite, and quartz, a metal material characterized by being one or more selected from metals frequently used as casting metals such as platinum or nickel, or graphite, and it is more preferable that the material of the melting mold is graphite in order to form the shape of the crystal and to smoothly separate the crystal from the melting mold.

[0033] The heat treatment method used in the heat treatment process is not particularly limited as long as it is a commonly used heat treatment method. However, it is preferable to adopt a heat treatment method using a general electric furnace in terms of economy, ease of handling, and equipment cost.

[0034] In the heat treatment process, the crushed material is preferably melted in the electric furnace at a temperature of 800 to 1250 ° C for 10 minutes to 2 hours. If the heat treatment temperature is lower than 800 ° C, the crushed material cannot be melted sufficiently, making it difficult to effectively produce the crystals, and if the heat treatment temperature is higher than 1250 ° C, the crushed material can be melted relatively effectively, but there is a problem of increased costs caused by using more energy than necessary, and a problem of having to separately use special high-temperature equipment due to the excessive temperature. In addition, if the heat treatment time is less than 10 minutes under the heat treatment temperature conditions, there is a problem of the crushed material cannot be melted sufficiently, making it difficult to effectively produce the crystals, and if the heat treatment time exceeds 2 hours, there is a problem of the quality of the final crystals being reduced due to excessive oxidation of the melting mold, as well as a problem caused by using more energy than necessary. The heat treatment time is preferably selected appropriately within the above time range depending on the size and shape of the crystals to be produced.

[0035] More specifically, the pulverized material to be melted is charged into the electric furnace when the temperature is 700 to 900°C, and the temperature is raised to a preset target temperature within the heat treatment temperature range. The heat treatment is then performed by maintaining the target temperature for a preset time within the heat treatment time range depending on the size and shape of the target crystal.

[0036] In the crystallization step (S15), the molten material that has been heat-treated in the heat treatment step (S14) is cooled to form a crystal. After the heat treatment is completed, the temperature in the electric furnace is lowered, and when the temperature reaches a discharge temperature through cooling, the molten mold is discharged from the electric furnace. If the molten mold is discharged from the electric furnace at a low temperature of about 750°C or less, there is a problem that magnetism occurs in the crystal, so the discharge temperature is 750 to 950°C, preferably 800 to 900°C.

[0037] The manufacturing method of ashes powder crystal according to one embodiment of the present invention may further include a separation and cleaning step (not shown) after the crystallization step (S15). The separation and cleaning step is characterized in that the molten mold discharged from the electric furnace is further cooled, the molten mold is separated, and foreign matter such as molten mold powder present on the surface of the molten mold is removed. In this case, if the molten mold is separated while the temperature is maintained at 100°C or higher, the shape of the molten mold may be distorted and phenomena such as cracks may be induced during the cleaning process. Therefore, it is preferable to separate the molten mold from the molten mold while the temperature of the molten mold is maintained within a temperature range of 10 to 100°C. The cleaning method is not particularly limited, but cleaning using ultrasonic waves is preferable to maintain the shape of the molten mold and minimize the occurrence of scratches.

[0038] The phosphoric acid obtaining step (S2) in the manufacturing method of ashes powder crystal according to the present invention will be described below with reference to Figures 2 and 3. The phosphoric acid obtaining step (S2) in the manufacturing method of ashes powder crystal according to the present invention is characterized by including a phosphorus reduction step (S21) of reducing and extracting phosphorus from ashes powder, a combustion step (S22) of burning and oxidizing the extracted phosphorus to form an oxide, and a hydration step (S23) of reacting the oxide with water to obtain phosphoric acid.

[0039] Although the composition of remains varies depending on the species, it is generally known that the remains have a composition of 55.82% calcium oxide (CaO), 42.39% phosphorus pentoxide (P2O5), and 1.79% water. The atomic weight of phosphorus (P) is 30.9738g / mol, so based on this, the phosphorus content in the remains accounts for about 25-30% of the total weight. Therefore, the remains themselves can be a good source of phosphorus, and the quality of the obtained phosphorus compound is not inferior at all to the currently commonly used method of obtaining phosphorus compounds from phosphorescent stones. Therefore, the manufacturing method of the remains powder crystal according to the present invention can reduce the manufacturing cost by further including a phosphoric acid obtaining step (S2) of obtaining phosphoric acid from the remains powder itself.

[0040] The phosphorus reduction step (S21) is a step of extracting phosphorus from the remains powder, and the extraction method is not particularly limited and may be any of the various conventionally known extraction methods, but is preferably characterized in that phosphorus is reduced and extracted from the remains powder using a tubular electric furnace that can freely create an inert atmosphere such as argon or helium, or a reducing atmosphere such as nitrogen, hydrogen, carbon dioxide, or carbon monoxide gas, in order to minimize oxidation due to heating.

[0041] In the combustion step (S22), the phosphorus extracted in the phosphorus reduction step (S21) is burned and oxidized to form an oxide. The oxide refers to various compounds in which phosphorus is oxidized, and preferably refers to phosphorus pentoxide (P2O5). When phosphorus is burned, it is oxidized to generally form phosphorus pentoxide (P2O5), and the reaction formula is as follows:

[0042] [Reaction Scheme 1] P4+5O2→2P2O5 The method for performing the combustion process in the combustion step (S22) is not particularly limited and may be any known combustion method.

[0043] In the hydration step (S23), the oxide formed in the combustion step (S22) is reacted with water to obtain phosphoric acid. As described above, the oxide is preferably phosphorus pentoxide, which reacts with water to form phosphoric acid according to the following reaction formula:

[0044] [Reaction Scheme 2] P2O5+3H2O→2H3PO4 Therefore, the method for producing ashes powder crystals including the phosphoric acid obtaining step (S2) is described in more detail in a chronological order. The phosphoric acid is obtained through the phosphoric acid obtaining step (S2) including the phosphorus reduction step (S21), the combustion step (S22) and the hydration step (S23), and the phosphoric acid obtained in the phosphoric acid obtaining step is mixed with ashes powder in a mixing step (S11), the mixture is dried to form a dried product in a drying step (S12), the dried product is crushed to form a crushed product in a subdivision step (S13), the crushed product is melted through a heat treatment process to form a melted product in a heat treatment step (S14), and the melted product is cooled to form a crystallization step (S15). The detailed description of the mixing step (S11), drying step (S12), subdivision step (S13), heat treatment step (S14) and crystallization step (S15) are as described above, so they will not be repeated below.

[0045] Hereinafter, a method for producing crystalline ashes powder according to another embodiment of the present invention will be described with reference to Fig. 4. The method for producing crystalline ashes powder according to another embodiment of the present invention further includes a classification step (S3) for classifying crystalline ashes powder into raw crystalline ashes powder and phosphorus-extracted crystalline ashes powder, and a phosphoric acid acquisition step (S2) for acquiring phosphoric acid from the phosphorus-extracted crystalline ashes powder, and is characterized in that the phosphoric acid used as a catalyst in the mixing step is the phosphoric acid acquired in the phosphoric acid acquisition step. Furthermore, the mixing step is characterized in that the raw crystalline ashes powder and the phosphoric acid acquired in the phosphoric acid acquisition step are mixed to form a second mixture.

[0046] In the classification step (S3), prior to the manufacturing process of the ashes powder crystal according to one embodiment of the present invention, the ashes powder from which the ashes powder crystal is to be manufactured is classified into raw ashes powder and phosphorus-extracted ashes powder. The raw ashes powder means ashes powder classified for use as the ashes powder to be mixed in the mixing step (S11) after the classification step (S3), and is preferably stored appropriately after the classification until it is used in the mixing step (S11), and the storage method is not particularly limited as long as it does not affect the physical or chemical properties of the ashes powder. Meanwhile, the phosphorus-extracted ashes powder means ashes powder classified for use as the ashes powder to be input to obtain the phosphoric acid in the phosphoric acid obtaining step (S2), and a detailed description of the method of obtaining the phosphoric acid from the phosphorus-extracted ashes powder through the process of reducing, burning, and hydrating the phosphorus-extracted ashes powder is omitted as it has been described above. On the other hand, the second mixture means a mixture obtained by mixing the raw remains powder and the phosphoric acid obtained in the phosphoric acid obtaining step (S2) in the mixing step (S11) as described above.

[0047] On the other hand, the mass of phosphoric acid obtained from the bone powder is almost the same as the mass of the bone powder added. This is because, as mentioned above, the phosphorus content in the bones accounts for about 25-30% of the total weight, the atomic weight of phosphorus is 30.9738g / mol, the atomic weight of oxygen (O) is 15.999g / mol, and the atomic weight of hydrogen (H) is 1.008g / mol, and one phosphoric acid molecule contains three hydrogen atoms, four oxygen atoms, and one phosphorus atom. Taking into account the atomic weights of phosphorus, oxygen, and hydrogen, the mass percentage (%) of phosphorus in one phosphoric acid molecule is about 31.6%, and when all of this is calculated, the mass of the phosphoric acid finally obtained is almost the same as the mass of the bone powder added. Therefore, based on these points, as described above, in the manufacturing method of bone powder crystals according to the present invention, the preferred mixing ratio in the mixing step (S11) is 100-200 weight parts of catalyst agent per 100 weight parts of bone powder, more preferably 100-180 weight parts of catalyst agent per 100 weight parts of bone powder, and even more preferably 160 weight parts of catalyst agent per 100 weight parts of bone powder, and therefore it is preferable that the classification ratio of the raw bone powder and the phosphorus-extracted bone powder also follows the above-mentioned weight part ratio.

[0048] Therefore, the method for producing ashes powder crystal according to another embodiment of the present invention will be described in more detail in a chronological manner. First, the ashes powder is classified into raw ashes powder and phosphorus-extracted ashes powder through the classification step (S3), and the phosphorus-extracted ashes powder is used to obtain the phosphorus, and then the phosphorus is mixed with the raw ashes powder to form a second mixture (S11), the second mixture is dried to form a dried product (S12), the dried product is crushed to form a crushed product (S13), the crushed product is melted through a heat treatment process to form a melted product (S14), and the melted product is cooled to form a crystallization step (S15). The phosphorus-acquisition step (S2), the drying step (S12), the dividing step (S13), the heat treatment step (S14), and the crystallization step (S15) are described above in detail. Therefore, this will be omitted below. In the case of the mixing step (S11), it differs from the above in that the raw remains powder and the phosphoric acid obtained through the phosphoric acid acquisition step (S2) are mixed to form a second mixture. However, as the detailed mixing method for forming the second mixture is no different from the mixing method described above, it will also be omitted below.

[0049] In another embodiment of the present invention, the method for producing ashes powder crystals can be characterized in that, after classifying ashes powder into raw ashes powder and phosphorus-extracted ashes powder, phosphoric acid extracted from the phosphorus-extracted ashes powder is mixed with the raw ashes powder to produce ashes powder crystals, transparent ashes powder crystals can be produced using only ashes derived from a single individual without adding any additional substances, so that ashes powder crystals can be produced that meet the fundamental intentions and requirements of the bereaved family or guardian who wants to commemorate the deceased, deceased companion animal or livestock by forming ashes powder crystals and preserve their remains, and that ashes powder crystals with excellent aesthetic value can be produced. At this time, the ratio of raw ashes powder and phosphorus-extracted ashes powder can be adjusted to adjust the content of phosphorus present in the crystals, and when the content of phosphorus is adjusted, the transparency of the transparent final crystals can be freely adjusted, thereby allowing the consumer to accurately realize and provide the desired transparency. For example, by adjusting the ratio of the raw ashes powder and the phosphorus-extracted ashes powder so that the phosphorus content in the crystal is about 30-40%, an opaque crystal can be obtained, by adjusting the ratio to about 40-50%, a translucent crystal can be obtained, and by adjusting the ratio to about 50-60%, a completely transparent crystal can be obtained. Figures 6 and 7 are photographs of crystals manufactured by the method for manufacturing ashes powder crystals according to another embodiment of the present invention, in which the phosphorus content in the crystal is different by adjusting the ratio of the raw ashes powder and the phosphorus-extracted ashes powder. As a result of component analysis of these crystals by XRF-ED, the phosphorus content of the translucent crystal shown in Figure 6 was 48%, and the phosphorus content of the completely transparent crystal shown in Figure 7 was 53%. This shows that the more transparent the crystal, the higher the phosphorus content.

[0050] The manufacturing method of the ashes powder crystal according to another embodiment of the present invention will be described below with reference to Fig. 5. The manufacturing method of the ashes powder crystal according to another embodiment of the present invention can further include a recovery step (S4) of recovering the residual ashes powder remaining after the phosphoric acid acquisition step (S2), and the mixing step (S11) is characterized in that the residual ashes powder recovered in the recovery step (S4) is mixed with phosphoric acid as the catalyst to form a third mixture, and preferably, the phosphoric acid as the catalyst mixed with the residual ashes powder in the mixing step (S11) is phosphoric acid obtained in the phosphoric acid acquisition step (S2).

[0051] In the recovery step (S4), the residual ashes powder remaining after the phosphorus component is extracted through the phosphoric acid acquisition step (S2) is recovered. Meanwhile, the third mixture refers to a mixture obtained by mixing the residual ashes powder with phosphoric acid as the catalyst or the phosphoric acid acquired in the phosphoric acid acquisition step (S2) in the mixing step (S11) as described above.

[0052] Therefore, to explain in more detail the manufacturing method of ashes powder crystal according to another embodiment of the present invention in a chronological order, first, the phosphoric acid is obtained by performing the phosphoric acid obtaining step (S2) using ashes powder, and then the recovery step (S4) is performed to recover the residual ashes powder from which the phosphorus component has been extracted through the phosphoric acid obtaining step (S2). The recovered residual ashes powder is then mixed with the phosphoric acid obtained in the phosphoric acid obtaining step (S2) in a mixing step (S11) to form a third mixture, a drying step (S12) to dry the mixture to form a dried product, a dividing step (S13) to pulverize the dried product to form a pulverized product, a heat treatment step (S14) to melt the pulverized product through a heat treatment process to form a molten product, and a crystallization step (S15) to cool the molten product to form a crystal. This method is characterized by finally producing an opaque ashes powder crystal. The detailed description of the phosphoric acid obtaining step (S2), drying step (S12), subdivision step (S13), heat treatment step (S14) and crystallization step (S15) are as described above, so they will be omitted below. In the case of the mixing step (S11), the residual ashes powder and phosphoric acid as the catalyst or phosphoric acid obtained through the phosphoric acid obtaining step (S2) are mixed to form a third mixture, which is different from the above-mentioned, but the third mixture is only different from the mixture and the second mixture formed in the mixing step in the manufacturing method for ashes powder crystal according to one embodiment of the present invention or the manufacturing method for ashes powder crystal according to another embodiment of the present invention in terms of components, etc., and the detailed mixing method for forming the mixture is the same as the above-mentioned mixing method, so it will be omitted below.

[0053] Another embodiment of the method for producing ashes powder crystals of the present invention involves extracting phosphoric acid from the entire ashes powder and then remixing the extracted phosphoric acid with the remaining ashes powder to produce ashes powder crystals. This means that opaque ashes powder crystals can be produced using only the remains derived from a single individual without adding any additional substances, so that ashes powder crystals can be produced that not only fulfill the fundamental intentions and demands of the bereaved family or guardians who wish to form ashes powder crystals to commemorate the deceased, dead companion animals or livestock and preserve their remains, but also have the characteristic of being able to produce ashes powder crystals that are excellent in aesthetic value.

[0054] Meanwhile, the ashes powder crystal produced using the residual ashes powder from which phosphorus components are extracted according to the manufacturing method for ashes powder crystal according to another embodiment of the present invention has an opaque form, unlike the ashes powder crystal produced using ashes powder from which phosphorus components are not extracted. This is because the composition of the ashes is as described in the detailed description of the manufacturing method for ashes powder crystal according to another embodiment of the present invention, and the residual ashes powder from which phosphorus components are extracted has a composition of calcium, oxygen, and hydrogen only, so that the third mixture formed in the mixing step (S11) using this has a lower phosphorus content than the mixture or the second mixture, and therefore the phosphorus content contained in the final ashes powder crystal is relatively lower than that of the ashes powder crystal produced by the manufacturing method according to one embodiment of the present invention or another embodiment of the present invention.

[0055] Therefore, by adjusting the residual phosphorus content of the residual ashes powder, the transparency of the final crystalline ashes powder can be freely adjusted. In the phosphorus acquisition step (S2), phosphorus components are reduced from the ashes powder through the phosphorus reduction step (S21). Therefore, by adjusting the phosphorus reduction process in the phosphorus reduction step (S21) to adjust the residual phosphorus content of the residual ashes powder, the transparency of the final crystalline ashes powder can be freely realized. The method of adjusting the residual phosphorus content of the residual ashes powder is not particularly limited as long as it corresponds to a method of adjusting the reduction process that can be used in various existing known extraction methods. As described above, when the phosphorus reduction step (S21) is performed using a tube-type electric furnace that can freely create an inert atmosphere or a reducing atmosphere, the residual phosphorus content of the residual ashes powder can be adjusted by adjusting the amount of reducing gas input to create the reducing atmosphere, or by adjusting the time of the process of reducing the ashes powder in the electric furnace, or by adjusting the internal temperature of the electric furnace.

[0056] In the following, preferred examples are presented to aid in understanding the present invention. However, the following examples are provided merely to facilitate understanding of the present invention and are not intended to limit the scope of the present invention.

[0057] <Example 1> After cremation, 100g of pulverized pig bone powder was mixed with 100mL of 85% aqueous phosphoric acid solution, which is available in the market, at 1000RPM for 2 minutes. The mixture was dried at 450℃ for 20 minutes to form a dried product, which was crushed to a size of 100Mesh and then placed in a melting mold. The melting mold was placed in an electric furnace at 700℃, heated to 1000℃ for 1 hour, and heat-treated at the same temperature for 20 minutes. The electric furnace was then cooled to 800℃, and then naturally cooled to room temperature. The ball-shaped crystals were separated from the cooled melting mold, and then washed with ultrasonic waves to obtain ball-shaped transparent crystals.

[0058] <Example 2> 1. 200g of pig bone powder obtained by crushing after cremation was separated into 85g of raw bone powder and 115g of phosphorus-extracted bone powder, and the 115g of phosphorus-extracted bone powder was placed in an electric furnace at a temperature of 1,350°C, and nitrogen and hydrogen gas were added, followed by reduction. The phosphorus obtained in this way was burned and reacted with flowing water to obtain about 110g of liquid phosphoric acid, and 25g of distilled water was added to the liquid phosphoric acid to obtain about 135g of 85% phosphoric acid aqueous solution. After reduction in the phosphoric acid extraction process, the remaining bone powder left in the electric furnace was separated and stored separately.

[0059] 2. Instead of pig bone powder, the raw bone powder classified separately in Example 2-1 was used, and instead of the phosphoric acid aqueous solution available on the market, the phosphoric acid aqueous solution obtained in Example 2-1 was used. Except for this, the other conditions were the same as in Example 1, and a transparent, ball-shaped single crystal agent 1 as shown in Figure 8 was obtained.

[0060] <Example 3> The remaining skeletal powder that had been separated and stored separately in Example 2-1 was used instead of the pig skeletal powder, and the phosphoric acid aqueous solution obtained in Example 2-1 was used instead of the phosphoric acid aqueous solution currently available on the market. Except for this, the other conditions were the same as in Example 1, and an opaque, ball-shaped single crystal agent 2 as shown in Figure 9 was obtained.

[0061] <Comparative Example 1> An attempt was made to produce crystals under the same conditions as in Example 1, except that the process was started by immediately drying only the pig bone powder without mixing the phosphoric acid aqueous solution with the pig bone powder. However, the crushed material did not melt properly, and ultimately no ball-shaped bone powder crystals were obtained.

[0062] <Comparative Example 2> An attempt was made to produce crystals under the same conditions as in Example 1, except that only 50 mL of phosphoric acid aqueous solution was used instead of 100 mL. However, in this case, the crushed material did not melt properly, and ultimately no ball-shaped remains powder crystals were obtained.

[0063] <Comparative Example 3> An attempt was made to produce crystals under the same conditions as in Example 1, except that only 150 mL of phosphoric acid aqueous solution was used instead of 100 mL. However, in this case, the crystals were not properly separated from the molten mold, and ultimately, no ball-shaped remains powder crystals were obtained.

[0064] <Comparative Example 4> Unlike Example 1, we attempted to produce crystals under the same conditions as Example 1, except that the heat treatment was carried out at a temperature of 750°C for 30 minutes.However, in this case, the crushed material did not melt properly, and ultimately, ball-shaped remains powder crystals were not obtained.

[0065] The applicant has described various embodiments of the present invention above, but these embodiments are merely examples that realize the technical ideas of the present invention, and any modifications or alterations that realize the technical ideas of the present invention should be construed as falling within the scope of the present invention.
