Powder

Abstract

A powder provides zirconia sintered bodies that contain manganese as a main coloring element, assume a black color, have high fracture toughness, and exhibit only a small variation in color tone due to different sintering temperatures; and a method for producing the powder. The powder contains zirconia containing yttrium as a stabilizing element, a manganese compound and alumina. The content of the stabilizing element in terms of oxide is 1.3 mol % or more and less than 2.0 mol % based on the total amount of the zirconia and the stabilizing element in terms of oxide. The content of the alumina is 0.2% by mass or more and 1.5% by mass or less based on the total mass of the powder, and the content of the manganese compound is 0.1% by mass or more and 0.6% by mass or less based on the total mass of the powder.
