Bright red cubic zirconium oxide crystal

Abstract

The invention relates to a bright red cubic zirconium oxide crystal. The bright red cubic zirconium oxide crystal is prepared from the following formula raw materials: 89 to 94 percent of zirconium dioxide, 3 to 8 percent of yttrium oxide, 1.5 to 3 percent of rare earth dicerium trioxide or cerium dioxide and 1.5 to 4 percent of neodymium oxide. The bright red cubic zirconium oxide crystal can beprepared by the steps of mixing the above formula raw materials uniformly, placing the mixture into a crucible, smelting, performing crystal pulling and cooling. The formula is unique, the special formula and the proportion of a coloring agent are selected, the problem that the bright red cannot be colored when the raw materials are at high temperature of 2700 DEG C is solved successfully, the blank that no cubic zirconium oxide crystal serves as nature-imitated ruby is filled, and when the bright red cubic zirconium oxide crystal is used for producing the nature-imitated ruby, the color is beautiful and bright and the nature-imitated ruby can be compared favorably with the natural ruby.

Description

technical field [0001] The invention relates to a cubic zirconia crystal, in particular to a large red cubic zirconia crystal, which belongs to the raw material for producing imitation natural ruby. Background technique [0002] At present, for the production of cubic zirconia crystals imitating natural gemstones, cubic zirconia crystals of various colors are available for them, but as the primary colors of red, blue and green, red has never been able to have products similar to natural rubies It can be successfully produced. In the past, only four colors of pink, orange, garnet, and purple can be produced, but they are far from the color of natural ruby. Contents of the invention [0003] The purpose of the invention is to invent a kind of big red cubic zirconia crystal which can produce imitation natural ruby ​​which is similar in color to natural ruby. [0004] The bright red cubic zirconia crystal of the present invention contains zirconia and yttrium trioxide raw mat...
