Abstract

The invention discloses a zirconium gemstone and a preparation method thereof, and belongs to the field of zirconium gemstones. The zirconium gemstone is prepared from 94 to 97 parts of cubic zirconia, 5 to 10 parts of stabilizing agent, 1 to 5 parts of stabilizer, and 1 to 10 parts of film agent, wherein the stabilizer is prepared from 20 to 30 parts of europium oxide, 30 to 50 parts of cerium oxide and 10 to 30 parts of neodymium fluoride; the film agent is anhydrous silica. The preparation method comprises the steps of melting and crystallizing cubic zirconia and the stabilizing agent to 90% to 98%, spraying the stabilizer in a molten state, recrystallizing, and coating the surface with a layer of film agent to protect the zirconium gemstone and reduce abrasion. At the same time, a silica film layer, which is colorless, transparent and thin, does not affect the color conversion rate of the zirconium gemstone and prolongs the service life of the zirconium gemstone.

Description

technical field [0001] The invention relates to the field of zircon gems, in particular to a zircon gem and a preparation method thereof. Background technique [0002] Gemstones are a kind of decoration that people like, and they are loved by people from all walks of life. Gemstones are divided into natural gemstones and artificial gemstones. Natural gemstones are rare and expensive, and it is difficult to meet market consumption needs. Therefore, artificial gemstones are mainly used to make up for market defects. Artificial gemstones are mainly artificial crystals, among which zirconia crystals are of the highest quality. However, whether it is single crystal silicon carbide or zirconia crystal, these artificial gemstones are easily worn out with the use in daily life, which makes the color of the gemstone dull and greatly shortens its service life. Contents of the invention [0003] The invention proposes a zircon gemstone and a preparation method thereof, and mainly s...
