Abstract
The invention discloses a material and an efficient method for the formation of a thermal-spray coating layer of a rare earth fluoride by a process of thermal-spray coating by using a unique thermal spray powder consisting of granules of the rare earth fluoride having a specified average particle diameter. The thermal-spray granules are prepared by granulating primary particles of the rare earth fluoride having a specified average particle diameter from an aqueous slurry containing a binder resin and subjecting the granules to a calcination treatment at a temperature not higher than 600° C.
