Description

[Technical Field]

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

[0002] Burial has traditionally been the primary method of interring the dead in Korea. However, each grave occupies an average of 15 square meters, and according to statistics, Korea uses an area of ​​land roughly half the size of Jeju Island as cemetery land. Furthermore, these graves are generally located in remote areas or in the mountains, making their management extremely difficult. Burial practices have fallen out of favor due to the limited space available and the constantly increasing value of land in Korea, as well as the changing social perceptions of funeral customs as modern society has become more Westernized and nuclearized. Cremation is gradually replacing this practice. Meanwhile, with the development of a pet-keeping culture, the practice of cremating companion animals, just like humans, is steadily increasing.

[0003] Generally, cremated remains are crushed into powder and placed in an ossuary, which is then stored in an open-air ossuary constructed of stone or other materials. When the remains are burned at high temperatures, they develop a porous structure with numerous microcavities, giving them a strong adsorption property. Therefore, they are prone to absorbing or adsorbing moisture, foreign matter, bacteria, etc. from the surrounding environment during storage, which can lead to deterioration and decay of the remains, generating a foul odor, and potentially damaging the remains due to the intrusion of pests.

[0004] To address these issues, several techniques have been proposed to process cremated remains to enhance their stability, while also adding aesthetic value and storage properties. These techniques allow for the preservation of the remains of deceased individuals or deceased companion animals. Conventional cremated remains conversion processes typically use direct gas flame or plasma processes. These methods utilize high temperatures (1,800–2,200°C) to melt the cremated remains, which become acidic, and the properties of high-melting-point quenching materials to produce gravel-like relics. However, these methods inevitably result in oxidation due to direct flame and loss of the cremated remains due to volatilization during the high-temperature process. Furthermore, there are also concerns about the potential for alteration after conversion. Conventional gemstone conversion techniques involve extracting specific elements from the cremated remains and mixing them with ruby ​​or sapphire for synthesis, or extracting carbon to create synthetic diamonds. However, even if this maintains aesthetic functionality in appearance, it uses only a small portion of the elements compared to the entire cremated remains powder as raw materials, which is quite different from the same funeral culture that places importance on preserving the remains, 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 cremation powder molding device" An apparatus for heat-treating cremated remains to produce spherical crystals, and a method for producing crystals using this apparatus have been disclosed. However, there is a problem in that heat-treating cremated remains at high temperatures of 1,800°C or higher may result in the cremated remains being lost due to volatilization.

[0006] <Patent Documents> Korean Patent Publication No. 10-2013-0082462 (Published July 19, 2013) "Method for storing cremated remains crystals mixed with charcoal composition" A method for producing crystallized remains with excellent antiseptic, deodorizing, and antibacterial properties has been disclosed, but there is a problem in that the content of bone powder in the crystallized 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 INVENTION

[0023] The method for manufacturing 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 person skilled in the art to which the present invention pertains, and in the event of a conflict with the meaning of a term used in this specification, the definition used in this specification shall prevail. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily distract from 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 manner commonly understood by a person of ordinary skill in the art to which the present invention belongs. Furthermore, commonly used terms defined in dictionaries should not be interpreted ideally or excessively unless expressly defined otherwise. Throughout the specification, when a part "comprises" a certain element, this does not mean that other elements are excluded, but that other elements may also be included, unless otherwise specified.

[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 vertebrates, but the term "bone meal" in this specification is preferably understood to mean a substance obtained by pulverizing the bone components remaining after the cremation of a deceased person, or a deceased companion animal or livestock.

[0026] Referring to Figure 1, the manufacturing method for cremated remains powder crystals according to one embodiment of the present invention is characterized by including a mixing step (S11) of mixing cremated remains powder with a catalyst to form a mixture, a drying step (S12) of drying the mixture to form a dried product, a dividing step (S13) of pulverizing the dried product to form a pulverized product, a heat treatment step (S14) of melting the pulverized product through a heat treatment process to form a molten product, and a crystallization step (S15) of cooling the molten product to form a crystalline product.

[0027] The mixing step (S11) refers to a step of uniformly mixing the ashes powder with the catalyst to form a mixture, and the mixing method for forming the mixture is not particularly limited, and can be performed by known mechanical mixing methods such as a ball mill, cutter mill, automatic mortar, bead mill, jet mill, or flat mill, or by manual mixing. In order to form a purer mixture, it is preferable to use a mixing tool made of a chemically resistant material such as quartz or Pyrex (registered trademark), but this is not necessarily limited to this.

[0028] The catalyst may be any material capable of forming a eutectic point lower than the melting temperature of the remains when mixed with the ashes. Preferably, it is a silicon compound, a boron compound, a phosphorus compound, or a mixture thereof. More preferably, it is a phosphorus compound selected from the group consisting of metaphosphoric acid (HPO), pyrophosphoric acid (HPO), phosphoric acid (HPO), their phosphate compounds, phosphorus pentoxide (P0), or a mixture thereof. More preferably, the catalyst is phosphoric acid (HPO). Phosphoric acid can act as a flux to lower the eutectic point during the ashes melting process. It also plays a vital role in activating phosphorus in the ashes to form crystals by utilizing its crystallization property at high concentrations. It can also prevent the loss of ashes due to volatilization caused by high temperatures, a major problem during the melting process. The transparency of the final crystals can be adjusted depending on the phosphorus content in the ashes.

[0029] In the mixing step (S11), the catalyst agent is phosphoric acid, as described above. The catalyst agent is preferably an 85% aqueous solution of phosphoric acid, and is mixed at 100 to 200 parts by weight per 100 parts by weight of the ashes powder. Preferably, the catalyst agent is mixed at 100 to 180 parts by weight per 100 parts by weight of the ashes powder. More preferably, the catalyst agent is mixed at 160 parts by weight per 100 parts by weight of the ashes powder. If the catalyst agent is mixed at less than 100 parts by weight per 100 parts by weight of the ashes powder, the ashes powder will not melt sufficiently, resulting in no crystal formation. If the catalyst agent is mixed at more than 200 parts by weight, the excessive phosphorus content will cause the molten material to erupt outside the melting mold during the subsequent heat treatment process, or the crystallization will not be releasable from the melting mold. The resulting crystals will have a flat shape, unlike a normal shape, which reduces aesthetic functionality. Meanwhile, in the mixing step (S11), 20 to 60 parts by weight of distilled water may be added to 100 parts by weight of the ashes powder in order to facilitate a smooth reaction between the ashes powder and the catalyst.

[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 subsequently produced.

[0031] In the dividing step (S13), the dried material formed in the drying step (S12) is pulverized to form a pulverized material. After completion of drying in the drying step (S12), the dried material exists in a solidified form like cement, and therefore must be divided into small pulverized materials for melting. Various known pulverization methods can be used in the dividing step (S13). However, to minimize loss of pulverized material during pulverization, it is preferable to use one or more methods selected from a disk mill, a ball mill, and a cutter mill. 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 molten material. The heat treatment process involves placing the pulverized material in a prepared melting mold and then melting the pulverized material through a heat treatment. The shape of the resulting crystal varies depending on the shape of the melting mold, so the shape of the melting mold can be selected as appropriate to the shape of the crystal to be produced. The melting mold material is preferably a ceramic material such as one or more selected from the group consisting of alumina, zirconia, mullite, and quartz; a metal material such as platinum or nickel, which is frequently used as a casting metal; or graphite. For crystal shape formation and smooth separation of the crystal from the melting mold, the melting mold material is more preferably graphite.

[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] During the heat treatment, the pulverized 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 pulverized material is not sufficiently melted, making it difficult to effectively produce a crystal. If the heat treatment temperature is higher than 1250°C, the pulverized material is melted relatively effectively, but the excessive energy consumption results in increased costs, and the excessive temperature necessitates the use of special high-temperature equipment. Furthermore, if the heat treatment time is less than 10 minutes under the above heat treatment temperature conditions, the pulverized material is not sufficiently melted, making it difficult to effectively produce a crystal. If the heat treatment time exceeds 2 hours, the excessive energy consumption results in excessive oxidation of the melting mold, resulting in a deterioration in the quality of the final crystal. The heat treatment time is preferably selected within the above range depending on the size and shape of the crystal to be produced.

[0035] More specifically, the heat treatment process is carried out by charging the pulverized material to be melted into the electric furnace when the temperature is 700 to 900°C, raising the temperature to a predetermined target temperature within the heat treatment temperature range, and then maintaining the target temperature for a predetermined 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 inside the electric furnace is lowered, and when the temperature reaches the discharge temperature, the molten mold is discharged from the electric furnace. If the molten mold is discharged from the electric furnace at a temperature below about 750°C, magnetization may occur in the crystalline material. Therefore, the discharge temperature is set to 750-950°C, preferably 800-900°C.

[0037] According to one embodiment of the present invention, the method for producing ashes powder crystals may further include a separation and cleaning step (not shown) after the crystallization step (S15). This separation and cleaning step involves further cooling the melting mold after it has been removed from the electric furnace, separating the crystals, and removing any foreign matter, such as melting mold powder, present on the crystals' surfaces. Separating the crystals while the melting mold temperature is maintained above 100°C can cause problems, such as distortion of the crystals' shape and the risk of cracking during the cleaning process. Therefore, it is preferable to separate the crystals from the melting mold while the melting mold temperature is maintained within the range of 10-100°C. While the cleaning method is not particularly limited, ultrasonic cleaning is preferred to maintain the shape of the crystals and minimize the occurrence of scratches.

[0038] The phosphoric acid obtaining step (S2) in the method for producing crystalline cremated remains powder according to the present invention will be described below with reference to Figures 2 and 3. The phosphoric acid obtaining step (S2) in the method for producing crystalline cremated remains powder according to the present invention is characterized by including a phosphorus reduction step (S21) in which phosphorus is reduced and extracted from cremated remains powder, a combustion step (S22) in which the extracted phosphorus is burned and oxidized to form an oxide, and a hydration step (S23) in which the oxide is reacted with water to obtain phosphoric acid.

[0039] While the composition of human remains varies depending on the species, it is generally known to consist of 55.82% calcium oxide (CaO), 42.39% phosphorus pentoxide (PO), and 1.79% water. The atomic weight of phosphorus (P) is 30.9738 g / mol, so based on this calculation, the phosphorus content of human remains accounts for approximately 25-30% of the total weight. Therefore, human remains can be a valuable source of phosphorus, and the quality of the phosphorus compounds obtained is in no way inferior to the currently common method of obtaining phosphorus compounds from phosphorescent stones. Therefore, the method for producing crystalline human remains powder according to the present invention further includes a phosphoric acid extraction step (S2) in which phosphoric acid is extracted from the human remains powder itself, thereby reducing production costs.

[0040] The phosphorus reduction step (S21) is a step of extracting phosphorus from the remains powder, and the extraction method is not particularly limited as long as it is one of the various conventionally known extraction methods. However, it is preferable to reduce and extract phosphorus 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 forms of compounds in which phosphorus is oxidized, but preferably refers to phosphorus pentoxide (PO). When phosphorus is burned, it is oxidized to generally form phosphorus pentoxide (PO), and the reaction formula is as follows:

[0042] [Reaction Scheme 1] P4+5O2→2P2O5 The method for carrying out 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), can be described in more detail in a chronological order as follows: phosphoric acid is obtained through the phosphoric acid obtaining step (S2), which includes 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 (S2) 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 pulverized to form a pulverized product in a dividing step (S13), the pulverized product is melted through a heat treatment process to form a molten product in a heat treatment step (S14), and the molten product is cooled to form a crystallization step (S15). Detailed descriptions of the mixing step (S11), drying step (S12), dividing step (S13), heat treatment step (S14), and crystallization step (S15) have been described above, so they will not be repeated below.

[0045] A method for producing crystalline cremated remains according to another embodiment of the present invention will be described below with reference to Figure 4. The method for producing crystalline cremated remains according to another embodiment of the present invention further comprises a classification step (S3) for classifying cremated remains into raw cremated remains powder and phosphorus-extracted cremated remains powder, and a phosphoric acid obtaining step (S2) for obtaining phosphoric acid from the phosphorus-extracted cremated remains powder, and the phosphoric acid used as a catalyst in the mixing step is the phosphoric acid obtained in the phosphoric acid obtaining step. Furthermore, the mixing step is characterized by mixing the raw cremated remains powder with the phosphoric acid obtained in the phosphoric acid obtaining step 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 refers to ashes powder classified for use as the ashes powder to be mixed in the mixing step (S11) after the classification step (S3). It is preferable that the raw ashes powder be appropriately stored after classification until it is used in the mixing step (S11). 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 refers to ashes powder classified for use as the ashes powder to be added to obtain phosphoric acid in the phosphoric acid obtaining step (S2). A detailed description of the method for obtaining phosphoric acid from the phosphorus-extracted ashes powder through the reduction, combustion, and hydration of the phosphorus-extracted ashes powder has been described above and will be omitted here. On the other hand, the second mixture refers to the 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] Meanwhile, the mass of phosphoric acid obtained from the cremated remains powder is roughly the same as the mass of the cremated remains powder added. This is because, as mentioned above, the phosphorus content in the cremated remains accounts for approximately 25-30% of the total weight, and the atomic weight of phosphorus is 30.9738 g / mol, the atomic weight of oxygen (O) is 15.999 g / mol, and the atomic weight of hydrogen (H) is 1.008 g / mol. 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 approximately 31.6%. This results in the mass of phosphoric acid obtained being roughly the same as the mass of the cremated remains powder added. Therefore, based on these points, as described above, in the manufacturing method of crystalline remains powder according to the present invention, the preferred blending ratio in the mixing step (S11) is 100 to 200 parts by weight of catalyst agent per 100 parts by weight of remains powder, more preferably 100 to 180 parts by weight of catalyst agent per 100 parts by weight of remains powder, and even more preferably 160 parts by weight of catalyst agent per 100 parts by weight of remains powder, and therefore it is preferable that the classification ratio of the raw remains powder and the phosphorus-extracted remains powder also follow the above-mentioned weight ratio.

[0048] Therefore, to explain in more detail the method for producing crystallized ashes powder according to another embodiment of the present invention in a chronological order, first, the ashes powder is classified into raw ashes powder and phosphorus-extracted ashes powder through the classification step (S3), the phosphorus-extracted ashes powder is used to obtain phosphoric acid through the phosphorus-extracted ashes powder acquisition step (S2), and then the phosphoric acid is obtained by mixing the obtained phosphoric acid with the raw ashes powder in a mixing step (S11), drying the second mixture to form a dried product in a drying step (S12), pulverizing the dried product to form a pulverized product in a dividing step (S13), melting the pulverized product through a heat treatment process to form a molten product in a heat treatment step (S14), and cooling the molten product to form a crystallization step (S15). The phosphoric acid acquisition step (S2), drying step (S12), dividing step (S13), heat treatment step (S14), and crystallization step (S15) are described in detail above. Therefore, we will omit this below. In the case of the mixing step (S11), there is a difference from the above in that the raw remains powder and the phosphoric acid obtained through the phosphoric acid obtaining step (S2) are mixed to form a second mixture. However, the detailed mixing method for forming the second mixture is the same as the above-mentioned mixing method, so we will also omit this below.

[0049] Another embodiment of the method for producing ashes powder crystals of the present invention involves separating ashes powder into raw ashes powder and phosphorus-extracted ashes powder, then mixing the phosphorus extracted from the phosphorus-extracted ashes powder with the raw ashes powder to produce ashes powder crystals. This allows for the production of transparent ashes powder crystals using only the remains of a single individual without the addition of any additional substances. This not only fulfills the fundamental intentions and needs of surviving family members or guardians who wish to commemorate and preserve the remains of a deceased person, deceased companion animal, or livestock by forming ashes powder crystals, but also produces ashes powder crystals with excellent aesthetic value. The ratio of raw ashes powder to phosphorus-extracted ashes powder can be adjusted to control the phosphorus content within the crystals. Adjusting the phosphorus content allows for the transparency of the final crystals to be freely adjusted, thereby enabling consumers to precisely achieve and provide the desired transparency. For example, by adjusting the ratio of raw cremated remains powder to phosphorus-extracted cremated remains powder so that the phosphorus content within the crystal is approximately 30-40%, opaque crystals can be obtained; by adjusting the ratio to approximately 40-50%, translucent crystals can be obtained; and by adjusting the ratio to approximately 50-60%, completely transparent crystals can be obtained. Figures 6 and 7 are photographs of crystals produced by a method for producing cremated remains powder crystals according to another embodiment of the present invention, in which the ratio of raw cremated remains powder to phosphorus-extracted cremated remains powder is adjusted to vary the phosphorus content within the crystals. Analysis of these crystals using XRF-ED revealed that the translucent crystal shown in Figure 6 had a phosphorus content of 48%, while the completely transparent crystal shown in Figure 7 had a phosphorus content of 53%. This indicates that the more transparent the crystal, the higher the phosphorus content.

[0050] A method for producing crystallized cremated remains powder according to another embodiment of the present invention will be described below with reference to Figure 5. The method for producing crystallized cremated remains powder according to another embodiment of the present invention can further include a recovery step (S4) for recovering the remaining cremated remains powder after the phosphoric acid obtaining step (S2), and the mixing step (S11) is characterized by mixing the remaining cremated remains powder recovered in the recovery step (S4) with phosphoric acid as the catalyst to form a third mixture, and preferably, the phosphoric acid as the catalyst mixed with the remaining cremated remains powder in the mixing step (S11) is the phosphoric acid obtained in the phosphoric acid obtaining step (S2).

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

[0052] Therefore, to explain in more detail the manufacturing method of ashes powder crystals 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 remaining ashes powder from which the phosphorus component has been extracted through the phosphoric acid obtaining step (S2). Then, the recovered residual ashes powder is mixed with the phosphoric acid obtained in the phosphoric acid obtaining step (S2) to form a third mixture (mixing step (S11)), the mixture is dried to form a dried product (drying step (S12)), the dried product is pulverized to form a pulverized product (dividing step (S13)), the pulverized product is melted through a heat treatment process to form a molten product (heat treatment step (S14)), and the molten product is cooled to form a crystalline product (crystallization step (S15)). This method is characterized by finally producing opaque ashes powder crystals. The detailed explanations of the phosphoric acid obtaining step (S2), drying step (S12), subdivision step (S13), heat treatment step (S14), and crystallization step (S15) have been described above, and will be omitted below. The mixing step (S11) differs from the above in that the residual ashes powder is mixed with phosphoric acid as the catalyst or phosphoric acid obtained through the phosphoric acid obtaining step (S2) to form a third mixture. However, the third mixture differs only in components from the mixture and the second mixture formed in the mixing step of the method for producing crystallized ashes powder according to one embodiment of the present invention or the method for producing crystallized ashes powder according to other embodiments of the present invention. The detailed mixing method for forming the mixture is the same as the above-described mixing method, and 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 re-mixing the extracted phosphoric acid with the remaining ashes powder to produce ashes powder crystals. This allows for the production of opaque ashes powder crystals using only the remains derived from a single individual without adding any additional substances. This not only satisfies the fundamental intentions and needs of the surviving family or guardians who wish to form ashes powder crystals to commemorate the deceased, their deceased companion animals, or livestock, and preserve their remains, but also allows for the production of ashes powder crystals that are excellent in aesthetic value.

[0054] Meanwhile, ashes powder crystals produced using the residual ashes powder from which phosphorus has been extracted according to the method for producing ashes powder crystals according to another embodiment of the present invention have an opaque appearance, unlike ashes powder crystals produced using ashes powder from which phosphorus has not been extracted. This is because the composition of the ashes is as described above in the detailed description of the method for producing ashes powder crystals according to another embodiment of the present invention, and the residual ashes powder from which phosphorus has been extracted contains approximately only calcium, oxygen, and hydrogen. Therefore, the third mixture formed in the mixing step (S11) using this has a lower phosphorus content than the first or second mixtures. As a result, the phosphorus content of the final ashes powder crystals is relatively lower than that of ashes powder crystals produced by the 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 extraction step (S2), phosphorus is 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 adjusted. The method for adjusting the residual phosphorus content of the residual ashes powder is not particularly limited as long as it corresponds to a reduction process adjustment method that can be used in various known extraction methods. As described above, when the phosphorus reduction step (S21) is performed using a tubular 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 introduced to create the reducing atmosphere, adjusting the time for the reduction process of the ashes powder in the electric furnace, or 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 100g of cremated pig bone powder was mixed with 100mL of commercially available 85% phosphoric acid solution at 1000 RPM for 2 minutes to form a mixture, which was then dried at 450°C for 20 minutes to form a dried product, which was then crushed to a 100 mesh size and placed in a melting mold. The melting mold was placed in an electric furnace at 700°C, heated to 1000°C over 1 hour, and heat-treated at that temperature for 20 minutes. The electric furnace was then cooled to 800°C, and the mold was allowed to cool naturally to room temperature. The ball-shaped crystals were separated from the cooled melting mold and then ultrasonically washed to obtain transparent ball-shaped crystals.

[0058] <Example 2> 1. 200g of pig bone powder obtained by pulverizing the cremated remains was separated into 85g of raw bone powder and 115g of phosphorus-extracted bone powder. The 115g of phosphorus-extracted bone powder was then placed in an electric furnace at 1,350°C, and nitrogen and hydrogen gas were added, followed by reduction. The resulting phosphorus was burned and reacted with flowing water to obtain approximately 110g of liquid phosphoric acid. 25g of distilled water was added to the liquid phosphoric acid to obtain approximately 135g of 85% aqueous phosphoric acid solution. After reduction in the phosphoric acid extraction process, the remaining bone powder remaining in the electric furnace was 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 currently 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, spherical single crystal agent 1 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 in the market. The other conditions were the same as in Example 1, and an opaque, spherical single crystal agent 2 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, ball-shaped bone powder crystals were not 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 cremation 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 cremation 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 cremation powder crystals were not obtained.
