摘要：
A thermal spray powder includes granulated and sintered yttria particles obtained by granulating and sintering a raw material powder in air or oxygen. The primary particles constituting the granulated and sintered yttria particles have an average particle size between 0.5 and 1.5 μm inclusive, and 1.11 times or more as large as the raw material powder. Alternatively, the primary particles have an average particle size between 3 and 8 μm inclusive.
