METHOD FOR PRODUCING ZIRCONIA PARTICLE-CONTAINING POWDER
The present invention provides a method for producing a zirconia particle-containing powder that enables easy production of a zirconia sintered body having both high translucency and high strength. The present invention relates to a method for producing a zirconia particle-containing powder, comprising a drying step of spray drying a slurry containing zirconia particles, wherein the zirconia particles have an average primary particle diameter of 30 nm or less, and the slurry comprises a dispersion medium containing a liquid having a surface tension at 25° C. of 50 mN/m or less. Preferably, the zirconia particles comprise 2.0 to 9.0 mol % yttria. Preferably, wherein the content of the liquid in the dispersion medium is 50 mass % or more.
