Disclosed herein is a zirconia porcelain which includes 1.5-5 mol % of yttrium oxide, 1-5.5 mol % of cerium oxide and the balance being substantially zirconium oxide. Disclosed herein also is a method of producing a zirconia porcelain, which includes the steps of preparing a mixed powder including 1.5-5 mol % of yttrium oxide, 1-5.5 mol % of cerium oxide and the balance being substantially zirconium oxide having an average particle size of less than 1.5 mu m when measured according to an air permeation method, shaping the mixed powder into a molding, and firing the molding thus at a temperature of 1,100 DEG C.-1,700 DEG C. |
