Description

Jewelry containing calcium mixed with precious metal and method for manufacturing the same

[0001] The present invention relates to jewelry in which calcium is mixed with a precious metal and a method for manufacturing the same, and more particularly, to jewelry in which calcium derived from a pet is mixed with a precious metal and a method for manufacturing the same, which is made by manufacturing the ashes remaining after the cremation of a pet into jewelry containing a high purity precious metal and which has a mechanical strength above a certain level, thereby serving as a memorial to owners mourning the death of their pets, satisfying the psychological satisfaction of the owners mourning and the value as jewelry, thereby maximizing consumer preference.

[0002] The term "companion animal" generally refers to an animal that lives alongside humans, a term given to pets like dogs and cats, reflecting their value to humans. Due to changing perceptions of companion animals and shifts in social climate, the number of people keeping pets in homes and other settings has been increasing exponentially.

[0003] Meanwhile, companion animals, as living beings, will eventually die. The number of dead animals is on the rise, and the disposal of these dead animals is becoming increasingly problematic. To address this issue, cremation is often the preferred method of disposal. Consequently, many pet owners choose to cremate their pets and then place the remains in a separate container.

[0004] However, the conventional method of storing and burying the remains of companion animals in a separate container has limitations in practical use due to the following problems.

[0005]

[0006] First, since the remains of companion animals become porous with a large number of microscopic pores when burned at high temperatures, they have strong adsorptive properties. This can cause deterioration or decay, resulting in a foul odor or damage to the remains by pests, as moisture, foreign substances, or bacteria from the surroundings are absorbed or adsorbed. To solve these problems, methods have been proposed to produce crystals by melting crushed remains at high temperatures or by mixing remains with minerals and heat-treating them. However, conventional methods for producing crystals using remains generally melt at very high temperatures of 1500°C to 3500°C. In this case, not only does it cause problems with excessive energy consumption, but it also causes problems with the durability of the devices and equipment due to repeated use at high temperatures, making it unsuitable for processing the remains of actual companion animals.

[0007]

[0008] Second, in order to improve the above problems, there have been attempts to manufacture jewelry by directly doping the remains of companion animals with precious metals, but the remains obtained from companion animals are already in a stable oxide form, making them difficult to selectively alloy with general precious metals. In addition, even if calcium or phosphorus, which are the main components of pet remains, were separated, the amount mixed in through diffusion was extremely small, limiting the ability to improve the strength of the jewelry, and thus limiting their practical use.

[0009]

[0010] Third, a method of mixing additional impurities has been proposed to improve the strength of jewelry made by mixing pet remains with precious metals. However, although this method can improve the strength of the jewelry to a certain level, there are problems such as a decrease in the aesthetic appeal of the jewelry, such as the gloss or color, or a decrease in the content of the precious metal depending on the content of the impurities mixed in, making it difficult to increase the value as jewelry, and thus limiting commercialization.

[0011]

[0012] Accordingly, the applicant has recently completed an invention for jewelry derived from a pet that can serve as a memorial for owners who mourn their pets after their death, and can satisfy the psychological satisfaction of owners in mourning and the value of jewelry, thereby maximizing consumer preference by solving the problem related to the current situation where the perception of pets has shifted to treating them as family members rather than animals, and the problem related to the disposal of pet remains that has expanded to the point of saturation, and by manufacturing the ashes remaining after the cremation of a pet into jewelry containing high-purity precious metals, but having a certain level of mechanical strength that can prevent breakage or deformation, etc.

[0013] The present invention has been devised to overcome the above-described problems, and the problem to be solved by the present invention is to provide jewelry and a method for manufacturing the same that can solve the problem related to the disposal of pet remains, which has expanded to the point of saturation due to the recent change in perception of pets to the point of treating them as family members rather than animals.

[0014] In addition, another problem that the present invention seeks to solve is to provide a jewelry and a method for manufacturing the same, which can be manufactured into jewelry containing high-purity precious metals from the ashes remaining after the cremation of a companion animal, but which can have a certain level of mechanical strength that can prevent breakage or deformation.

[0015] In addition, another problem that the present invention seeks to solve is to provide jewelry derived from pets and a method for manufacturing the same, which can serve as a memorial for owners mourning their pets after their death, and which can satisfy the owners' psychological satisfaction in mourning and the value as jewelry, thereby maximizing consumer preference.

[0016] The present invention provides a method for manufacturing jewelry in which calcium and a precious metal are mixed, comprising a first step of obtaining calcium chloride from remains, a second step of electrolyzing calcium chloride (CaCl2) to obtain solid calcium, and a third step of mixing the calcium with a precious metal and melting it to solve the above-described problem.

[0017] Additionally, according to one embodiment of the present invention, the calcium chloride of the second step may be characterized as being derived from animal remains.

[0018] Additionally, the precious metal may be characterized as being gold (Au) or silver (Ag).

[0019] In addition, it may be characterized in that after the second step, the third step is performed after mixing the solid calcium with copper (Cu).

[0020] Additionally, the content of the calcium may be characterized as being 0.1 to 5 wt%.

[0021] Additionally, the content of the precious metal may be characterized as being 95 to 99.9 wt%.

[0022] Additionally, the third step may be characterized in that it is performed at a temperature of 950 to 1150 ℃.

[0023] In addition, the present invention provides a jewelry in which calcium (Ca) and a precious metal are mixed, wherein calcium is included in an amount of 0.1 to 5 wt% and the precious metal is included in an amount of 95 to 99.9 wt% based on the total weight of the jewelry.

[0024] In addition, it can be characterized by satisfying the following relationships (1) to (3).

[0025] (1) 40 ~ 100 Hv Vickers hardness

[0026] (2) Tensile strength of 250 to 300 MPa

[0027] The present invention extracts calcium from the remains of a companion animal through a relatively simple and rapid process and alloys it with precious metals, thereby providing a memorial for owners mourning their companion animals after their deaths. It also maximizes the content of precious metals while maintaining high mechanical strength, thereby significantly enhancing psychological satisfaction and value as jewelry, thereby greatly improving consumer satisfaction.

[0028] Figure 1 is an image showing a method of mixing calcium chloride obtained from conventional bone with precious metals.

[0029] FIG. 2 is an image of jewelry manufactured according to one embodiment of the present invention.

[0030] Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0031]

[0032] As described above, the conventional method of manufacturing jewelry from the remains of common pets is difficult to increase in value as jewelry due to limitations in strength enhancement, gloss, color, and precious metal content, and is disadvantageous in terms of commercialization because it requires a process that maintains high temperatures and high pressures.

[0033] Accordingly, the present invention seeks to solve the above-described problem by providing a method for manufacturing jewelry in which calcium (Ca) and a precious metal are mixed, comprising a first step of reacting an oil obtained from remains with HCl to obtain calcium chloride; a second step of electrolyzing calcium chloride (CaCl2) to obtain solid calcium; and a third step of mixing the calcium with a precious metal and melting it.

[0034] Through this, the present invention can greatly enhance consumer satisfaction by extracting calcium from the remains of a pet and alloying it with precious metals through a relatively simple and rapid process, thereby providing a memorial for owners mourning their pets after their death, and maximizing the content of precious metals while maintaining high mechanical strength, thereby greatly enhancing psychological satisfaction and value as jewelry.

[0035]

[0036] The present invention will be described in detail below.

[0037]

[0038] Jewelry manufacturing method

[0039] The first step of the method for manufacturing jewelry mixed with calcium and precious metals according to the present invention is a step of crushing cremated remains to obtain powdered oil, mixing it with HCl and titrating it to obtain CaO+2HCl -> CaCl2+H2O, and then drying it to obtain calcium chloride (CaCl2). The first step can be performed at a temperature of 25 to 80°C. Thereafter, the second step is a step of obtaining solid calcium by melting and electrolyzing calcium chloride at a high temperature.

[0040] Previously, methods for producing crystals by high-temperature melting of crushed bone powder or mixing bone powder and minerals and heat-treating them have been proposed. However, these crystal production methods generally melt at very high temperatures of 1500℃ to 3500℃, which not only causes problems with excessive energy consumption but also with the durability of the equipment and devices due to repeated use at high temperatures, making them unsuitable for processing the remains of actual pets. In addition, in the case of the method of first heat-treating the remains at a temperature of 1600℃, then collecting the remains and heat-treating them a second time at a temperature of 1700℃ to completely melt the remains, and then putting the melted remains in water to cool them to produce crystals, there is the problem that it takes about 4 hours or more to melt bone powder mainly composed of calcium phosphate, which results in high costs.

[0041] Even if the above-mentioned problems can be improved, there is a problem in that the calcium component is not selectively mixed in the method of directly mixing calcium chloride obtained from remains with pure gold at a temperature of 1150℃ and maintaining it as a melt and mixing with precious metals. More specifically, as shown in Fig. 1, when high-purity gold and calcium chloride obtained from remains are mixed and melted at a temperature of approximately 1100℃, it can be seen that the gold and calcium are not sufficiently mixed, making selective alloying of calcium with gold impossible, which can also be confirmed through the results of Spark Emission Spectroscopy (SES) component analysis.

[0042] Ultimately, if calcium chloride derived from pet remains is mixed in liquid form according to the conventional method, it does not form an alloy with precious metals, and there are problems such as excessive energy consumption and durability of devices and equipment due to repeated use at high temperatures, making it unsuitable for processing actual pet remains.

[0043]

[0044] Accordingly, the present invention can solve the above-described problem by obtaining solid calcium by melting and electrolyzing calcium chloride at high temperature in the second step.

[0045] At this time, the electrolysis of the second stage is not particularly limited as a known conventional electrolysis method may be used as long as it is suitable for the purpose of the present invention, but according to one embodiment of the present invention, calcium chloride derived from animal remains may be electrolyzed to obtain solid calcium, and electrolysis may be performed in the following order.

[0046] More specifically, when molten calcium chloride derived from animals is injected into the cell of the electrolysis device and the temperature of the entire system is maintained at 772℃ or higher, it melts into a conductive liquid phase, and when current is applied to the electrolysis device at this time, calcium chloride is decomposed in the cathode cell and separated into calcium ions, which are then recovered as a single calcium metal.

[0047] At this time, according to a preferred embodiment of the present invention, the electrolysis conditions of the electrolysis may be a current density of 1 to 200 A / cm2 and an electrolysis temperature of 700 ℃ to 800 ℃. At this time, if the current density is less than 1 A / cm2, there may be a problem that the recovery rate of metallic calcium at the cathode is low, and if the current density exceeds 200 A / cm2, there may be a problem that the heat generation of the cathode becomes excessive or it is difficult to control the temperature of the electrolytic bath. In addition, among the electrolysis conditions, the electrolysis temperature is performed in the range of 700 ℃ to 800 ℃. Normally, 772 ℃ is the melting point of pure calcium chloride, but in the present invention, melting is possible even at 700 ℃ due to the mixing of other impurities, and if it is 800 ℃ or higher, an oxide layer may be formed on the surface of the electrode metal, which may lower the decomposition yield, so the proposed appropriate temperature range is maintained.

[0048] In addition, the electrolysis may be performed in an inert gas atmosphere. When performed in an inert gas atmosphere, metallic calcium is generated at the cathode of the cathode cell, and chlorine gas is discharged from the anode cell. Therefore, the yield of calcium can be improved by controlling the atmosphere to an inert gas atmosphere to prevent oxidation of the easily oxidized calcium in the cathode cell. At this time, the inert gas is preferably argon.

[0049]

[0050] Meanwhile, according to one embodiment of the present invention, after the second step, the third step can be performed after mixing the solid calcium with copper (Cu).

[0051] Generally, when making jewelry using only calcium and precious metals as the main ingredients, it can be disadvantageous in terms of strength and cost-effectiveness. For example, calcium derived from animals has a Mohs hardness of about 1.75, and precious metals also have a relatively low hardness of about 2.5 to 3. Therefore, when making jewelry by mixing these, to achieve a certain level of strength, a large amount of gold, which has a relatively high hardness, must be used, which causes uneconomical results and is practically disadvantageous for commercialization. Even if the above-mentioned problems are solved and commercialization is achieved, the soft nature of precious metals in general may still cause the strength to be low enough to be used in jewelry.

[0052] Accordingly, the present invention can provide an economic feasibility suitable for commercialization as jewelry by alloying the solid calcium with copper to create a master alloy after the second step and performing the third step, and can also obtain an excellent effect in terms of strength.

[0053] More specifically, in order to mix the solid calcium obtained in the second step with copper, a known conventional mixing method may be adopted as long as it suits the purpose of the present invention, and is not particularly limited thereto. However, more preferably, the solid calcium obtained in the second step is put into a copper molten metal (1100°C or higher) and the calcium powder is wrapped in copper foil and then put in, or the electrode portion and the remaining calcium chloride mixture from the second step are all put into the molten metal, so that the copper for the electrode is naturally mixed into the copper base material, and the calcium chloride acts as a flux and blocks the copper molten metal from reacting with oxygen in the atmosphere, so that the copper base alloy can be manufactured.

[0054]

[0055] Next, the third step of the method for manufacturing jewelry mixed with calcium and precious metal according to the present invention is a step of mixing the calcium obtained in the second step with the precious metal and melting it.

[0056] The above precious metal may be any precious metal commonly used in jewelry that meets the purpose of the present invention, without limitation. For example, it may be a platinum group element (palladium, platinum, iridium, rhodium, ruthenium, osmium) excluding nickel, as well as mercury, rhenium, titanium, beryllium, tungsten, chromium, and more preferably gold (Au) or silver (Ag). In this case, it may be reasonable from a cost perspective for commercialization, and may have appropriate compatibility with calcium.

[0057] At this time, if the precious metal is gold or silver, the third step can be performed at a temperature of 950 to 1150°C. At this time, if the temperature of the third step is lower than 950°C, there may be a problem that the gold or silver does not melt, and if the temperature of the third step exceeds 1150°C, there may be a problem that the calcium element, which is easily oxidized, is oxidized first.

[0058] In addition, according to one embodiment of the present invention, when the precious metal is gold or silver, the content of the calcium may be 0.1 to 5 wt%, and preferably 0.5 to 2 wt%. In this case, if the content of the calcium is less than 0.1 wt%, there may be a problem that the mechanical strength of the precious metal jewelry is low, almost similar to that when calcium is not mixed, and further, if the content of the calcium exceeds 5 wt%, due to the excessive amount of calcium, brittle intermetallic compounds such as Au4Ca or Ag9Ca2 are generated, so the mechanical strength of the jewelry is easily reduced and color change occurs, so there may be a limit to increasing the value as jewelry.

[0059] In addition, according to one embodiment of the present invention, when the precious metal is gold or silver, the content of the precious metal may be 95 to 99.9 wt%. In this case, if the content of the precious metal is less than 95 wt%, there may be a limit to increasing the value as jewelry, and if the content of the precious metal exceeds 99.9 wt%, it is difficult to distinguish between the hardness and strength properties of 99.99% pure precious metal, making it difficult to determine whether calcium is mixed, so that excessive precious metal is used, which is disadvantageous in terms of economy, and in particular, there may be a problem that the mechanical properties of the jewelry are not improved because the content of calcium is limited to an extremely small amount. In addition, the calcium and precious metal may be mixed in a weight part of 0.1 to 5:95 to 99.9.

[0060]

[0061] Jewelry

[0062] Next, a jewelry according to the present invention will be described. However, to avoid duplication, descriptions of parts that are identical to the manufacturing method and technical concepts of the jewelry described above will be omitted. The jewelry according to the present invention is a jewelry that is a mixture of calcium and a precious metal, and contains 0.1 to 5 wt% of calcium and 95 to 99.9 wt% of the precious metal based on the total weight of the jewelry. More preferably, the calcium content may be 0.5 to 2 wt% based on the total weight of the jewelry.

[0063] As described above, the present invention aims to maximize the content of precious metals while maintaining high mechanical strength by extracting calcium from the remains of a companion animal through a relatively simple and rapid process and alloying it with precious metals, thereby greatly enhancing psychological satisfaction and value as jewelry. According to a preferred embodiment of the present invention, jewelry including the content of calcium and the content of precious metals can satisfy both of the following relationships.

[0064] (1) 40 ~ 100 Hv Vickers hardness

[0065] (2) Tensile strength of 200 to 300 MPa

[0066]

[0067] At this time, if the Vickers hardness of the above relational expression (1) is less than 40 Hv, the probability of burrs occurring during jewelry manufacturing increases, and due to the soft nature, durability may decrease during manufacturing and wearing, making it difficult to increase the value as jewelry. In addition, if the Vickers hardness of the above relational expression (1) exceeds 100 Hv, there may be a problem that the hardness is too high, making cutting difficult, or breaking due to external impact during wearing.

[0068] Meanwhile, if the tensile strength of the above relational expression (2) is less than 200 MPa, there may be a problem that the ductility of the manufactured jewelry is too great and can be easily deformed. In addition, if it exceeds 300 MPa, when the consumer is subjected to external stress while wearing the product, the product may not break, but rather the wearer's skin may be damaged.

[0069] Hereinafter, the present invention will be described in more detail through examples, but the following examples do not limit the scope of the present invention, and should be interpreted as helping to understand the present invention.

[0070]

[0071] Example 1 - Manufacturing of Jewelry

[0072] The cremated remains were crushed to obtain powdered remains, which were then mixed with HCl to obtain calcium chloride, and the calcium chloride was subjected to an electrolysis process under conditions of a current density of 100 A / cm2 and an electrolysis temperature of 772°C in an argon atmosphere to obtain solid calcium.

[0073] Next, the obtained calcium was placed in an alumina crucible and melted by maintaining it in an electric furnace at 1150°C for 10 minutes, then drawn into a wire rod and processed, and a ring was manufactured using a rolling technique, as shown in Fig. 2. The calcium and gold contents are as shown in Table 1 below.

[0074]

[0075] Examples 2 to 5 - Manufacturing of jewelry

[0076] A ring was manufactured in the same manner as in Example 1 above, but with different weights of calcium and gold as shown in Table 1 below.

[0077]

[0078] Comparative Example - Jewelry Manufacturing

[0079] A ring was manufactured in the same manner as in Example 1 above, but a ring without calcium was manufactured as shown in Table 1 below.

[0080] Calcium (weight part) Gold (weight part) Example 10.0899.92 Example 20.399.7 Example 3199 Example 4397 Example 55.594.5 Comparative Example 0100

[0081] Experimental Example 1 - Hardness Evaluation Hardness measurements (Fisherscope, HM2000) were performed for the above Examples 1 to 5 and Comparative Examples, and the results are shown in Table 2 below.

[0082] Classification Vickers hardness (Hv) Example 140 Example 268 Example 381 Example 471 Example 569 Comparative Example 35

[0083] Experimental Example 2 - Tensile Strength Evaluation Tensile strength (AND ATC-1150A) evaluation was performed on the above Examples 1 to 5 and Comparative Example, and the results are shown in Table 3 below.

[0084] Tensile strength (MPa) Example 1223 Example 2242 Example 3268 Example 4254 Example 5249 Comparative Example 211

[0085] Experimental Example 3 - Component Evaluation Component evaluation was performed using SES (Bruker, Q8 Magellan) for the above Examples 1 to 5 and Comparative Examples, and the major elements are shown in ppm units in Table 4 below.

[0086] ClassificationCaAgPdCuExample 1875.20.10.10.1Example 23253.30.10.10.1Example 39528.30.10.10.1Example 427982.60.10.10.1Example 556237.10.10.10.1Comparative Example 0.10.10.10.1

[0087] Referring to Tables 1 to 4 above, it can be seen that in Example 1, where calcium is included below the lower limit of the numerical range of the present invention, both the Vickers hardness and tensile strength show low values, and in the case of the comparative example that does not include calcium, the values ​​are significantly lower.

[0088] Meanwhile, among Examples 2 to 4 in which calcium satisfies the numerical range of the present invention, Example 3 is found to have the best Vickers hardness and tensile strength. This is because brittle Au4Ca is generated in Example 4, resulting in lower mechanical strength than Example 3. Discoloration also occurs due to such intermetallic compounds, making it difficult to manufacture into jewelry.

[0089] In particular, in the case of Example 5, the amount of calcium was excessive, and mechanical properties were deteriorated due to the influence of the intermetallic compound, and discoloration also occurred.
