Title:
ZIRCONIA CERAMIC, IN VIVO IMPLANT, FIRING POWDER, AND METHOD FOR PRODUCING ZIRCONIA CERAMIC
Document Type and Number:
WIPO Patent Application WO/2024/080382
Kind Code:
A1
Abstract:
The zirconia ceramic according to an embodiment has a crystal structure comprising zirconium, silver, and oxygen ions. The method for producing a zirconia ceramic according to an embodiment includes a sediment formation step (S1) and a firing step (S3). In the sediment formation step (S1), a zirconium compound and a silver compound are mixed in a solution or suspension state and a precipitant is then added to the solution or suspension, thereby obtaining a sediment comprising zirconia derived from the zirconium compound and silver derived from the silver compound. In the firing step (S3), a firing powder obtained by drying the sediment is fired to obtain a zirconia ceramic with which silver ions have combined.
