SCANDIA-STABILISED ZIRCONIA SINTERED POWDER, PROCESS FOR PRODUCTION OF SCANDIA-STABILIZED ZIRCONIA SINTERED POWDER, PROCESS FOR PRODUCTION OF SCANDIA-STABILIZED ZIRCONIA SHEET
The process for production of a scandia-stabilized zirconia sheet according to the present invention is characterized in comprising the steps of pulverizing a scandia-stabilized zirconia sintered body to obtain a scandia-stabilized zirconia sintered powder having an average particle diameter (De) determined using a transmission electron microscope of more than 0.3 µm and not more than 1.5 µm, and an average particle diameter (Dr) determined by a laser scattering method of more than 0.3 µm and not more than 3.0 µm, and a ratio (Dr/De) of the average particle diameter determined by the laser scattering method to the average particle diameter determined using the transmission electron microscope of not less than 1.0 and not more than 2.5; preparing a slurry containing the scandia-stabilized zirconia sintered powder and a zirconia unsintered powder, wherein a percentage of the scandia-stabilized zirconia sintered powder to a sum of the scandia-stabilized zirconia sintered powder and the zirconia unsintered powder in the slurry is not less than 2 mass% and not more than 40 mass%; forming the slurry into a greensheet; and sintering the greensheet.
