PRODUCTION METHOD FOR WORKABLE ZIRCONIA COMPOSITE SINTERED BODY, RAW MATERIAL COMPOSITION FOR WORKABLE ZIRCONIA COMPOSITE SINTERED BODY, AND WORKABLE ZIRCONIA COMPOSITE CALCINED BODY
The present invention provides a method that enables fabrication of a machinable zirconia composite sintered body that is machinable in a sintered state while maintaining properties suited for dental use, in a shorter time than it is possible with conventional methods. The present invention relates to a method for producing a machinable zirconia composite sintered body, comprising the steps of: fabricating a molded body with a raw material composition that comprises 78 to 95 mol% of ZrO2 and 2.5 to 10 mol% of Y2O3, and 2 to 8 mol% of Nb2O5 and/or 3 to 10 mol% of Ta2O5, and in which ZrO2 predominantly comprises a monoclinic crystal system; and sintering the molded body.
