PROBLEM TO BE SOLVED: To provide a zirconia powder which is excellent in moldability, has a high sintering density, and can produce a color zirconia sintered body by a simple method. SOLUTION: Zirconia containing itria in the range of 2 mol% or more and 6 mol% or less, and one or more oxides selected from the group consisting of Group 4 to Group 9, Group 12, Group 14 and lanthanoid elements. A zirconia powder having a pore volume of 0.14 to 0.28 mL / g and a relative molding density of 44 to 55% when molded at a molding pressure of 1 t / cm 2 . [Selection diagram] None |
