ABSTRACT:
A thermal spray powder contains particles composed of an oxide of any of the rare earth elements having an atomic number of 39 or from 59 to 70. The crushing strength of the particles is 80 MPa or greater. The ratio of bulk specific gravity to true specific gravity of the thermal spray powder is 0.15 or greater. The particles are preferably granulated and sintered particles. The average particle size of primary particles constituting the granulated and sintered particles is preferably 6 μm or less.
