Abstract

The invention relates to the technical field of artificial gemstone production, in particular to an energy-saving artificial gems and a preparation method thereof; the energy-saving artificial gem isobtained according to the following method: aluminum powder, metal titanium powder, metal chromium powder, metal iron powder, metal nickel powder, metal vanadium powder, titanium oxide powder, chromium oxide powder, iron oxide powder, nickel oxide powder and vanadium oxide powder are mixed and then conveyed into a crystal growth chamber through oxygen; after hydrogen is input, combustion aluminumpowder and oxygen react to generate aluminum oxide liquid drops, the aluminum oxide liquid drops drop on seed crystals in the crystal growth chamber to obtain crystals, a seed crystal lifting table slowly rotates and gradually descends until crystal growth of the crystals is finished, and the energy-saving artificial gem is obtained. The preparation method is simple and convenient, process conditions are easy to meet, high-purity and high-density colored gems with different components and different colors can be obtained, hobbies and requirements of different customers are met, and the production process is energy-saving and environment-friendly and meets national environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of artificial gemstone production, and relates to an energy-saving artificial gemstone and a preparation method thereof. Background technique [0002] Artificial gemstones are often used in consumer electronics such as watch dials and jewelry because of their high hardness, high density, and high refractive index. In order to improve the appreciation, it is also necessary to add different colors to the gemstones to meet the preferences and requirements of different customers. In the existing production of artificial gemstones, the melting method uses alumina powder to pass through a high-temperature hydrogen-oxygen flame to melt the alumina powder, and the molten droplets are cooled during the falling process and solidify on the seed crystal to gradually grow into crystals, but there is production consumption Disadvantages of high energy and high environmental protection costs; in the Kyropoulos method, onl...
