Method for producing processed zirconia composite sintered body, raw material composition of formable zirconia composite sintered body and synthetic zirconia compound calcite

摘要

The present invention provides a method of preparing a sintered zirconia composite sintered body having a suitable property for dental use and capable of machining in the sintering state in a short time compared to the conventional method.The present invention includes 78 to 95 mol% ZrO2, 2.5 to 10 mol% Y2O3, 2 to 8 mol% Nb2O5 and / or 3 to 10 mol% of Ta2O5 The present invention relates to a method of producing a processing zirconia composite sintered body including a process of producing a molded body using a raw material composition having a monoclinic system and a main crystal system of ZrO. Sub.2, and sintering the molded body.
