Abstract
A thermal spray powder contains granulated and sintered yttria particles and fine yttria particles, the average particle diameter of the fine yttria particles being no more than 1 μm. The content of the fine yttria particles in the thermal spray powder is 1,000 to 10,000 ppm by mass. It is preferred that the thermal spray powder be used in applications for forming a thermal spray coating by plasma thermal spraying at atmospheric pressure.
