Description

[Technical Field]

[0001] This invention relates to a method for producing crystalline cremated remains powder, specifically, a method for producing crystalline cremated remains powder using phosphoric acid (H3PO4) as a catalyst in the heat treatment process of the cremated remains powder, preventing the loss of the cremated remains powder due to volatilization and allowing for more efficient crystal formation. More specifically, by producing crystalline cremated remains powder by mixing phosphoric acid obtained by reducing phosphorus in the cremated remains with cremated remains powder, it is possible to provide crystalline cremated remains powder consisting only of the pure components of the cremated remains themselves without the need for additional additives, thereby satisfying the needs of surviving family members or guardians who wish to store crystalline cremated remains powder consisting only of the pure cremated remains powder of the deceased or deceased companion animal.Furthermore, by freely achieving the color and transparency of the final crystalline cremated remains powder in a single manufacturing process, it is possible to satisfy the aesthetic needs of consumers and to easily utilize it in various jewelry. [Background technology]

[0002] Burial has traditionally been the primary method of burial in Korea. Each gravesite occupies an average of 59.2 m² (15 pyong). Statistics show that in Korea, an area equivalent to half the size of Jeju Island is used as a cemetery. Furthermore, these gravesites are often located in remote or mountainous areas, making their management difficult. Burial practices have declined due to the limited space available and the constantly increasing value of land in Korea. Furthermore, modern society has become increasingly Westernized and nuclearized, resulting in significant changes in social perceptions of funeral customs. They are gradually being replaced by cremation. Furthermore, with the development of a culture of pet ownership, the practice of cremating companion animals, just like humans, is steadily increasing.

[0003] Generally, cremated remains are crushed and placed in a cinerary box as powdered bones and stored in an outdoor ossuary or stone masonry. When the remains are burned at high temperatures, they develop a porous structure with numerous micropores, giving them strong adsorption properties. Therefore, during storage, they absorb or adsorb moisture, foreign matter, bacteria, and other substances from the surrounding environment, causing deterioration and decay of the remains, generating foul odors, and being susceptible to damage 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 at the same time adding aesthetic value and storability, allowing the remains of deceased individuals or deceased companion animals to be preserved. Conventional cremated remains conversion processes typically use direct gas or plasma methods. These methods utilize high temperatures (1,800-2,200°C) to melt the cremated remains, resulting in acidification, and the high melting point of the quenching material to produce gravel-like relics. However, these methods inevitably result in the loss of cremated remains due to volatilization, as well as the potential for deterioration after conversion. Furthermore, in the case of conventional gemstone technology, methods have been proposed in which only specific elements from the cremated remains are extracted and mixed with rubies and sapphires to synthesize them, or carbon is extracted to create artificial diamonds. While these methods are aesthetically and functionally superior in appearance, they use only a very small number of elements compared to whole cremated remains as raw materials, which is quite different from Eastern funeral culture, which places importance on preserving the remains. As a result, the fundamental purpose of these technologies cannot be achieved.

[0005] Patent Document 1 discloses an apparatus for heat-treating cremated remains to produce ball-shaped crystals, and a method for producing crystals using the apparatus. However, there is a problem in that the cremated remains are heat-treated at high temperatures of 1,800°C or higher, resulting in the loss of the cremated remains due to volatilization. Patent Document 2 discloses a method for producing crystalline ashes that has excellent antiseptic, deodorizing, and antibacterial properties. However, the manufacturing process involves adding a considerable amount of substances such as charcoal, ceramics, seven precious stones, and tourmaline, which results in a problem of a low content of bone powder in the crystalline ashes.

DETAILED DESCRIPTION OF THE INVENTION

[0031] Hereinafter, the method for manufacturing crystallized ashes powder according to the present invention will be described in detail 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 if there is a conflict with the meaning of a term used in this specification, the definition used in this specification will prevail. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted.

[0032] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification may be used in a manner commonly understood by a person of ordinary skill in the art to which the present invention belongs. Furthermore, terms defined in commonly used dictionaries should not be interpreted ideally or excessively unless clearly defined otherwise. Throughout this specification, when a part "comprises" a certain element, this does not exclude other elements, and means that other elements may also be included, unless otherwise specified.

[0033] On the other hand, bone meal is generally a common name for the substance obtained by pulverizing the bone components remaining in the corpse of a vertebrate, but the term "bone meal" in this specification is preferably understood to mean the substance obtained by pulverizing the bone components remaining after the cremation of a deceased person, a dead companion animal, or livestock.

[0034] 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 crushing step (S13) of crushing the dried product to form a crushed product, a heat treatment step (S14) of melting the crushed product through a heat treatment process to form a molten product, and a crystallization step (S15) of cooling the molten product to form a crystal.

[0035] 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 applied, for example, known mechanical mixing methods such as a ball mill, cutter mill, automatic mortar, bead mill, jet mill, plate mill, etc., or it can be easily mixed manually. 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 this is not necessarily limited to this.

[0036] The catalyst is not particularly limited as long as it can be mixed with the ashes powder to form a eutectic point lower than the melting point of the ashes themselves, and is preferably a silicon compound, a boron compound, a phosphorus compound, or a mixture thereof. More preferably, it is metaphosphoric acid (HPO), pyrophosphoric acid (HPO), phosphoric acid (HPO), these phosphate compounds, phosphorus pentoxide (PPO), etc. 10 ) or mixtures thereof, and more preferably, the catalyst is phosphoric acid (H3PO4). Phosphoric acid can act as a flux that lowers the eutectic point during the ashes powder melting process, and at the same time, it can play an intimate role in forming crystals by activating the phosphorus in the ashes powder, taking advantage of its property of crystallization when its concentration becomes high, and can also play a role in preventing the loss of ashes powder due to volatilization that occurs under high temperature conditions, which is one of the main problems that occur during the melting process.

[0037] 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 and crystals will not form. If the catalyst agent is mixed at more than 200 parts by weight, the excessive phosphorus content will cause the molten material to be ejected outside the melting mold during the subsequent heat treatment process, or the crystallization will not be easily releasable from the melting mold. The resulting crystals will have a flat shape that is different from the normal shape, reducing 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 further facilitate the reaction between the ashes powder and the catalyst.

[0038] 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. The drying temperature or drying time is preferably set appropriately depending on the amount and state of the mixture. If the drying is insufficient or excessively proceeded, it may affect the pattern and transparency of the crystals to be subsequently formed.

[0039] In the pulverizing step (S13), the dried material formed in the drying step (S12) is pulverized to form a pulverized material. The dried material after drying in the drying step (S12) exists in a solidified form like cement, and must be pulverized to obtain small pulverized material for melting. Various known pulverizing methods can be used in the pulverizing 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.

[0040] In the heat treatment step (S14), the pulverized material formed in the pulverization step (S13) is melted by heat treatment to form a molten material. The heat treatment involves placing the pulverized material in a prepared melting mold and then melting the pulverized material by heat treatment. Since the shape of the resulting crystal varies depending on the shape of the melting mold, the shape of the melting mold can be selected arbitrarily depending on the shape of the crystal to be produced. The melting mold material is preferably a ceramic material characterized by at least one selected from the group consisting of alumina, zirconia, mullite, and quartz, a metal material characterized by one or more selected from metals frequently used as casting metals, such as platinum or nickel, or graphite. For the purpose of forming a pattern on the crystal and smoothly separating the crystal from the melting mold, the melting mold material is more preferably graphite.

[0041] 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 use a heat treatment method using a general electric furnace in terms of economy, ease of handling, and equipment cost.

[0042] The heat treatment process is preferably carried out by melting the pulverized material 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 cannot be sufficiently melted, making it difficult to effectively produce a crystal. If the heat treatment temperature is higher than 1250°C, the pulverized material can be melted relatively effectively, but the excessive energy consumption results in high 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 heat treatment temperature conditions, the pulverized material cannot be sufficiently melted, making it difficult to effectively produce a crystal. If the heat treatment time exceeds 2 hours, in addition to the excessive energy consumption, excessive oxidation of the melting mold can result in poor 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.

[0043] More specifically, the heat treatment process is carried out by introducing 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 pattern of the desired crystals.

[0044] 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, the crystalline material may become porcelain. Therefore, the discharge temperature is set to 750-950°C, preferably 800-900°C.

[0045] According to one embodiment of the present invention, a method for manufacturing ashes powder crystals may further include a separation and cleaning step (not shown) following the crystallization step (S15). This separation and cleaning step involves further cooling the melting mold after it is removed from the electric furnace, separating the crystals, and removing any foreign matter, such as melting mold powder, present on the crystals' surface. Separating the crystals while the melting mold temperature is maintained above 100°C can cause problems, such as distortion of the crystal's pattern 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 crystal's pattern and minimize scratches.

[0046] The phosphoric acid obtaining step (S2) in the method for producing crystallized 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 crystallized cremated remains powder according to the present invention is characterized by including a phosphorus reduction step (S21) in which phosphorus is extracted by reducing it 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.

[0047] The remains vary in some respects depending on the species, but generally consist of 55.82% calcium oxide (CaO) and 42.39% phosphorus pentoxide (PO 10), and 1.79% water. The atomic weight of phosphorus (P) is 30.9738 g / mol, so based on this calculation, the phosphorus content in cremated remains accounts for approximately 25-30% of the total weight. Therefore, cremated remains themselves can be a good source of phosphorus, and the quality of the obtained phosphorus compounds is in no way inferior to the currently common method of obtaining phosphorus compounds from phosphate rock. Therefore, the method for producing crystallized cremated remains powder according to the present invention can reduce production costs by further including a phosphoric acid obtaining step (S2) in which phosphoric acid is obtained from the cremated remains powder itself.

[0048] The phosphorus reduction step (S21) is a step of extracting phosphorus from the cremated remains powder. The extraction method is not particularly limited and may be any of the various extraction methods known in the art. Preferably, to minimize oxidation due to heating, phosphorus is reduced and extracted from the cremated 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, or carbon dioxide gas.

[0049] 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, phosphorus pentoxide (PO 10 When phosphorus is burned, it is oxidized to form phosphorus pentoxide (PO 10 ) and the scheme is as follows:

[0050] [ka]

[0051] The method for carrying out the combustion process in the combustion step (S22) is not particularly limited and may be any known combustion method.

[0052] 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 scheme:

[0053] [ka]

[0054] Therefore, the method for producing ashes powder crystals, including the phosphoric acid obtaining step (S2), will be explained in more detail in a chronological order. The method includes the phosphorus reduction step (S21), the combustion step (S22), and the hydration step (S23), and includes obtaining phosphoric acid through the phosphoric acid obtaining step (S2), mixing the phosphoric acid obtained through the phosphoric acid obtaining step with ashes powder (S11), drying the mixture to form a dried product (S12), crushing the dried product to form a crushed product (S13), melting the crushed product through a heat treatment process to form a molten product (S14), and crystallizing the melted product to form a crystal (S15). The detailed description of the mixing step (S11), drying step (S12), pulverizing step (S13), heat-treating step (S14), and crystallization step (S15) is the same as that described above, and therefore will be omitted below.

[0055] Next, a method for manufacturing crystalline cremated remains according to another embodiment of the present invention will be described with reference to Figure 4. The method for manufacturing crystalline cremated remains according to another embodiment of the present invention further comprises a classification step (S3) for separating cremated remains into raw cremated remains and phosphorus-extracted cremated remains, and a phosphoric acid obtaining step (S2) for obtaining phosphoric acid from the phosphorus-extracted cremated remains, 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 and the phosphoric acid obtained in the phosphoric acid obtaining step to form a second mixture.

[0056] In the classification step (S3), prior to the manufacturing process of ashes powder crystals according to one embodiment of the present invention, the ashes powder from which ashes powder crystals are 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 the classification step (S3) and before use 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 the phosphoric acid in the phosphoric acid obtaining step (S2). A detailed description of the method for obtaining the phosphoric acid from the phosphorus-extracted ashes powder by reducing, burning, and hydrating the phosphorus-extracted ashes powder is omitted, as it is the same as that described above. As mentioned above, the second mixture refers to the mixture obtained by mixing the raw remains powder with the phosphoric acid obtained in the phosphoric acid obtaining step (S2) in the mixing step (S11).

[0057] The mass of phosphoric acid obtained from the cremated remains powder is approximately equal to the mass of the cremated remains powder added. This is because, as mentioned above, the phosphorus content in cremated remains accounts for approximately 25-30% of the total weight, 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 ratio (%) of phosphorus in one phosphoric acid molecule is approximately 31.6%. When all these factors are taken into account, the mass of phosphoric acid obtained is approximately equal to the mass of the cremated remains powder added. Therefore, based on this point, in the manufacturing method of crystalline remains powder according to the present invention, as mentioned above, the preferred mixing 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.

[0058] 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, ashes powder is classified into raw ashes powder and phosphorus-extracted ashes powder in the classification step (S3), and phosphorus is obtained by using the phosphorus-extracted ashes powder in the phosphorus-extracted ashes powder to obtain phosphorus. Then, in a mixing step (S11), the obtained phosphorus is mixed with the raw ashes powder to form a second mixture, in a drying step (S12), the second mixture is dried to form a dried product, in a crushing step (S13), the dried product is crushed to form a crushed product, in a heat treatment step (S14), the crushed product is melted by a heat treatment process to form a molten product, and in a crystallization step (S15), the melted product is cooled to form a crystallization product, which is characterized by the method including the final production of light blue or colorless transparent ashes powder crystals. Detailed explanations of the phosphoric acid obtaining step (S2), drying step (S12), crushing step (S13), heat treatment step (S14), and crystallization step (S15) are the same as those described above, so they will be omitted below. The mixing step (S11) differs from the above in that the raw remains powder and the phosphoric acid obtained by the phosphoric acid obtaining step (S2) are mixed to form a second mixture, but the detailed mixing method for forming the second mixture is the same as the above-mentioned mixing method, so it will also be omitted below.

[0059] In another embodiment of the method for producing ashes powder crystals, the ashes powder is separated into raw ashes powder and phosphorus-extracted ashes powder, and then the phosphoric acid extracted from the phosphorus-extracted ashes powder is mixed with the raw ashes powder to produce ashes powder crystals. This allows for the production of light blue or colorless transparent ashes powder crystals using only the ashes themselves from a single individual without the need to add any additional substances. This satisfies the fundamental intentions and needs of the surviving family or guardians who wish to create ashes powder crystals to commemorate the deceased, their deceased companion animals, or livestock and preserve their remains, while also allowing the production of ashes powder crystals that are excellent in aesthetic value.

[0060] Next, a method for manufacturing crystallized remains powder according to another embodiment of the present invention will be described with reference to Figure 5. The method for manufacturing crystallized remains powder according to another embodiment of the present invention can further include a recovery step (S4) for recovering the remaining remains powder remaining after the phosphoric acid recovery step (S2), and the mixing step (S11) is characterized by mixing the remaining 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 remains powder in the mixing step (S11) is the phosphoric acid obtained in the phosphoric acid recovery step (S2).

[0061] In the recovery step (S4), the remaining 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 remaining 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.

[0062] 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 phosphoric acid is obtained by performing the phosphoric acid obtaining step (S2) using ashes powder, and then the remaining ashes powder is recovered by performing the recovering step (S4) to extract the phosphorus component in the phosphoric acid obtaining step (S2). Then, the recovered remaining 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 crushed to form a crushed product (Crushing step (S13)), the crushed product is melted by a heat treatment process to form a molten product (Heat treatment step (S14)), and the melted product is cooled to form a crystallization step (S15), which finally produces a green or white opaque crystallized ashes powder. Detailed explanations of the phosphoric acid obtaining step (S2), drying step (S12), crushing step (S13), heat treatment step (S14), and crystallization step (S15) are the same as those described above, so they will be omitted below. In the case of the mixing step (S11), it differs from the above in that the remaining remains powder is mixed with phosphoric acid as the catalyst or phosphoric acid obtained by the phosphoric acid obtaining step (S2) to form a third mixture. However, the third mixture differs only in its constituent components from the mixture and the second mixture formed in the mixing step in the method for producing crystallized remains powder according to one embodiment of the present invention or the method for producing crystallized remains 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, so it will also be omitted below.

[0063] Another embodiment of the method for producing ashes powder crystals according to the present invention involves extracting phosphoric acid from all the ashes powder, and then mixing the extracted phosphoric acid with all the remaining ashes powder to produce ashes powder crystals. This means that an opaque green or white ashes powder crystals can be produced using only the ashes themselves from a single individual, without the need to add any additional substances. This ashes powder crystals fulfill the fundamental intentions and needs of the surviving family or guardians who wish to commemorate the deceased, deceased companion animal, or livestock and preserve their remains, and are also characterized by the ability to produce ashes powder crystals that are excellent in aesthetic value. However, this method is not limited to this, and it will be obvious to those skilled in the art that various modifications are possible, such as extracting only phosphoric acid from ashes powder as needed, and then extracting phosphoric acid from other individuals and mixing it with the remaining ashes powder.

[0064] Meanwhile, ashes powder crystals produced using the remaining ashes powder from which phosphorus has been extracted by the method for producing ashes powder crystals according to another embodiment of the present invention have an opaque green or white appearance, unlike ashes powder crystals produced using ashes powder from which phosphorus has not been extracted. This is thought to be due to the fact that the composition of the ashes is as explained in the detailed explanation of the method for producing ashes powder crystals according to another embodiment of the present invention, so the remaining ashes powder from which phosphorus has been extracted has a composition consisting mainly of calcium, oxygen, and hydrogen. Therefore, the third mixture formed in the mixing step (S11) has a lower phosphorus content than the first or second mixtures. As a result, the phosphorus content in the final ashes powder crystals is relatively lower than that of ashes powder crystals produced by the method for producing ashes powder crystals according to one embodiment of the present invention or other embodiments.

[0065] Therefore, by adjusting the residual phosphorus content of the remaining ashes powder, the color and transparency of the final crystalline remains can be freely controlled. The phosphorus component in the phosphorus extraction step (S2) is reduced from the ashes powder in 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 remaining ashes powder, the color and transparency of the final crystalline remains can be freely controlled. The method for adjusting the residual phosphorus content of the remaining ashes powder is not particularly limited as long as it corresponds to the method for adjusting the reduction process used in various known extraction methods. As described above, when the phosphorus reduction step (S21) is performed using a tubular electric furnace capable of freely creating an inert or reducing atmosphere, the residual phosphorus content of the remaining ashes powder can be controlled 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.

[0066] Preferred embodiments of the present invention will be presented below to aid in understanding the present invention. However, the following embodiments are provided merely to facilitate understanding of the present invention, and the contents of the present invention are not limited to the embodiments. [Example]

[0067] 100g of cremated pig bone powder was mixed with 100mL of a commercially available 85% aqueous 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 allowed to cool naturally to room temperature. The ball-shaped crystals were then released from the cooled melting mold and ultrasonically cleaned to obtain transparent, light blue ball-shaped crystals. [Example]

[0068] 1. 200g of pig bone powder obtained by grinding the bones after cremation 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 and reduced. The obtained phosphorus was burned and reacted with running 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. The remaining bone powder remaining in the electric furnace after reduction in the phosphoric acid extraction process was stored separately. 2. The raw skeletal powder classified 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 commercially available phosphoric acid aqueous solution. The other conditions were the same as in Example 1, and a single crystal 1 with a light blue, transparent, ball-like shape as shown in Figure 6 was obtained. [Example]

[0069] The remaining skeletal powder that had been separated and stored 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 commercially available phosphoric acid aqueous solution. The other conditions were the same as in Example 1, and a green, opaque, ball-shaped single crystal 2 as shown in Figure 7 was obtained.

[0070] <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 the pig bone powder without mixing the phosphoric acid solution with the pig bone powder. However, the crushed material could not be properly melted, and ultimately, ball-shaped bone powder crystals were not obtained.

[0071] <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 could not be properly melted, and ultimately, ball-shaped cremation powder crystals could not be obtained.

[0072] <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 could not be properly released from the molten mold, and ultimately, no ball-shaped cremated remains powder crystals were obtained.

[0073] <Comparative Example 4> Unlike Example 1, the heat treatment was carried out at 750°C for 30 minutes, but other conditions were the same as in Example 1 to attempt to produce crystals. However, in this case, the crushed material could not be properly melted, and ultimately, ball-shaped cremation powder crystals could not be obtained.

[0074] The applicant has described various embodiments of the present invention above, but these embodiments are merely one embodiment that realizes the technical idea of ​​the present invention, and any modified examples or examples that realize the technical idea of ​​the present invention should be interpreted as falling within the scope of the present invention.
