More particularly, single crystals are grown by using a single crystal growing method, and then processed into the shape of ornaments using the prepared single crystals to form single crystal ornaments. The present invention relates to a method for producing jewelry and to single crystal jewelry.

In general, single crystals have a regular arrangement of atoms, ions, and molecules in a solid, and their internal atomic arrangements have a regular and complete structure. Such a single crystal has a high gloss and deep color due to the regular arrangement of internal atoms, and there is no lattice defect and the gloss lasts long. In addition, since the structure is perfect, it is harder than ordinary metal.

Among these metal single crystals, in particular, single crystals made of silver (Ag) are expected to have very excellent characteristics as compared to silver as a general metal. In particular, in the case of jewelry such as silver necklaces or silver rings sold on the market there is a disadvantage that the deformation easily occurs such as discoloration or pitted after a certain time. When the silver single crystal ornaments are produced by the growth of silver single crystals, which are not castings, such as silver ornaments, in particular, there is no discoloration which is an advantage of the single crystal, and the gloss can be maintained for a long time and can be solved.

Particularly, in the case of conventional pure gold or pure silver, it has a soft property, so it is deformed by external pressure to form a delicate pattern or cannot combine other gemstones, resulting in a lack of aesthetics, thereby failing to satisfy various needs of consumers. .

Therefore, the present invention has been made to solve the above problems of the prior art, the seed crystals are used to grow the metal single crystal and then processed to process the metal single crystal into the shape of various ornaments to produce single crystal ornaments An object of the present invention is to provide a method for producing jewelry and single crystal jewelry.

In order to achieve the above object, the present invention, after receiving the gold or silver in the growth crucible, by heating and melting the gold or silver contained in the growth crucible, using a seed crystal having a crystal structure as a seed Czochralski or bridge A single crystal growing step of growing the single crystal by the Bay method; A first outer shape forming step of cutting the grown single crystal to form a first outer shape; Forming a second outer shape after forming the first outer shape; A surface polishing step of polishing the surface after forming the secondary outline; The pattern forming step of forming a pattern on the surface after the surface polishing; and the single crystal ornaments manufacturing method characterized in that it comprises a and the single crystal ornaments produced thereby are the technical gist.

In addition, the primary shape forming step is preferably processed into the shape of a disk, cylinder or rectangular parallelepiped from the grown single crystal, and it is also preferably processed into a predetermined shape by wire cut or lathe processing.

In addition, the secondary shape forming step, it is preferable to process into a ring, semi-circular ring or rectangular parallelepiped shape, furthermore, it is a predetermined shape by one method during the wire cut, lathe processing or press working using a mold having a pattern. It is preferable to be processed into.

In addition, the pattern forming step, it is preferable that the intaglio or embossed pattern is formed, it is preferable that the jewelry is coupled to the pattern.

In addition, it is preferable to form a coupling hole penetrating back and forth after the secondary appearance forming step to be coupled to a necklace, bracelet, earrings, and the like.

As a result, single crystal ornaments are manufactured from single crystals grown by using the excellent gloss and color, which are inherent in single crystals, and harder properties than ordinary metals, and not only replace existing precious metals, but also display different tastes. There is a possible advantage.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

First, a metal mass (gold, silver) to be grown is put in a growth crucible (BN crucible, quartz crucible, graphite crucible, alumina crucible, etc.), and the induction heating or carbon using the induction coil is used as a growth crucible containing the metal mass. The metal mass is melted using a heater. In the present invention, a graphite crucible is used as a growth crucible, or a double crucible using a graphite crucible as an external crucible and one of a BN crucible, a quartz crucible, and an alumina crucible is used as an inner crucible.

In the present invention, a method for growing a silver single crystal will be described in detail.

Since silver does not chemically bond with carbon, a growth crucible was used as a graphite crucible or a double structure crucible in which an external crucible is a graphite crucible. The reason why the growth crucible is used as a heating element is that it is difficult to control the temperature of induction heating when the metal single crystal is grown and the amount of lumps in the molten state remaining in the crucible is reduced. Therefore, controlling the temperature of the crucible itself by using the growth crucible as a heating element is easy to cultivate the metal single crystal. Growth crucibles and ordinary silver are inductively heated to the melting point of the metal using RF coating. Since the melting point of silver is 962 ℃, it is completely dissolved by heating it to a temperature about 30 ℃ higher than the melting point.

And seed crystals having a desired crystal structure were prepared to grow single crystal seeds by the Czochralski method, and seed crystal single crystal seeds were prepared in the shape of rods in the directions of (100), (110), and (111), respectively. In addition, the growth temperature was carried out in the range of 1000 ℃ to 900 ℃ to grow the silver single crystal, by using the Czochralski method using a single crystal seed, which is a seed crystal that grows while controlling the liquid temperature about 0.1 ~ 1 ℃ / min Foster high purity single crystals of silver.

In the above, the method for growing the single crystal by the Czochralski method has been described, but the single crystal may be formed by the Bridgman method.

Next, to produce jewelry using the grown single crystal (10), the process for the wire-cut (100) processing of the grown high-purity single crystal to the desired thickness by performing electrical discharge machining or turning The primary outer shape is formed by cutting into a disc, cylindrical, or cuboid shaped piece of. According to the design of the ornaments to be finally made here, it is formed in a shape close to this. In the case of a disc shape or a cylindrical shape, the shape of the final ornament is round, semi-circular, ring, semi-ring or thin but various complex designs are primary. It is formed by the appearance. In the case of a rectangular parallelepiped shape, when the design of the ornament to be finally made is a rectangular parallelepiped or a similar shape, it is formed as a primary appearance.

In addition, the thickness of the disc-shaped piece is determined depending on the width of the jewelry to be manufactured. If the ring is manufactured with jewelry, it is cut to an appropriate thickness in consideration of the final design.

After the outer shape is formed primarily from the single crystal 10 grown as described above, the case of manufacturing an open ring-shaped pendant according to an embodiment of the present invention will be described.

As shown in Fig. 1, single crystals 10 grown from seed crystal single crystal seeds are cut into disc-shaped pieces with a wire-cut 100, and then the disc-shaped pieces are cut using an external molder. After fixing, the shape of the pendant is secondarily formed by using wire-cut 100 electric discharge machining. Here, for mass production, by fixing a plurality of disc-shaped pieces to an external molder or by fixing a conductive adhesive to a holder, a plurality of disc-shaped pieces can be simultaneously processed by wire-cut 100 discharge. Allow large pendants to be produced at one time.

In addition to the electrical discharge machining by the wire-cut (100), the same shape as the pattern shape of the mold is processed by placing the disk-shaped pieces on the upper surface of the mold formed with the desired pattern and then press working. . Ring-shaped ornaments are formed in the case of the ring-shaped pattern, and square ornaments are formed in the case of the metal-shaped mold. Moreover, it can also form in a predetermined shape by lathe processing.

And after forming the secondary shape to be coupled to the necklace or bracelet string as a pendant to form a coupling hole 20 penetrating back and forth using the wire drill machine (200).

When the external appearance of the jewelry is completed, the surface of the jewelry is polished with the polishing brush 300 so as to give a gloss inherent in the single crystal.

In addition, after the polishing operation, the embossed or engraved pattern 30 may be further formed on the outer surface of the pendant by the demand of the consumer, and the pattern forming method may be implemented by fine laser processing or handicraft. In addition, the intaglio pattern or the embossed pattern 30 may combine natural gemstones of various colors, that is, natural gemstones such as diamond, synthetic gemstones, artificial gemstones, and the like. After processing the place where the jewel is to be put in the usual way during processing, it is fixed by holding the girdle (girdle) that is the widest part of the jewel, or using a method of bonding using an adhesive.

1 is a diagram illustrating a manufacturing process of a ring-shaped pendant opened with such single crystal ornaments, and FIG. 2 is a diagram illustrating a manufacturing process of a tetrahedron-shaped pendant according to another embodiment. In the case of a rectangular parallelepiped pendant, the grown single crystal 10 is cut into a rectangular parallelepiped shape to form a primary external shape, and a secondary external shape which is a final shape is formed using the single crystal 10. Figure 3 is a view showing a picture of manufacturing a real single crystal and a rectangular parallelepiped, an open ring and a ring-shaped pendant by processing it.

The present invention is not limited to the above embodiments, and can form various ornaments of the desired design when forming the secondary appearance, and it is possible to manufacture pendants, rings, earrings, hairpins, buttons, and various accessories made of single crystals. As a result of the characteristics of the single crystal, excellent gloss and deep color, no discoloration, and firmness are supported to replace the existing precious metals, and there is an advantage of expressing a different taste.

In addition, in the case of a ring-shaped ring manufactured by the above method may be utilized as an auxiliary role to help human health. In the case of a single crystal ring in which the metal atoms are unidirectional in the ring shape, the change in the magnetic field induced by the current flowing inside the ring shape or the eddy current induced by the change in the magnetic field will increase more than in the general metal ring. In the case of a single crystal ring with a unidirectional crystal structure, the disturbance of the current is reduced due to structural stabilization, so that the amount of current induced in the ring shape is larger than that of a general ring shape ring.

Therefore, the amount of eddy current generated in the single crystal ring stimulates the body's blood flow smoothly, and when the biomagnetic change accumulates with time due to the change of blood flow, the change of blood flow is more active than the general person. Will be there. Consistent with current medicine, it is conducive to the health of the human body if the flow of blood is constant and always active.

The present invention by the above configuration is to produce a single crystal ornaments from single crystals grown using the excellent gloss and color, and the harder properties than ordinary metals, which are inherent to single crystals, and can replace existing precious metals, It is possible to express the sense of beauty.
