Synthesis of Black Cubic Zirconia Single Crystals

摘要

The present invention relates to a black cubic phase of zirconia single crystal manufacturing method, and more particularly zero-phase stabilizing calcium oxide (CaO) or yttrium oxide (Y ₂ O ₃₎ To this was added a colorless or colored, such as a single crystal of a cubic phase of zirconia and heat treated in a carbon reducing atmosphere, a vacuum hot relates to a process for producing as an artificial jewel black cubic phase zirconia single crystal.
