Abstract: A material for cold spraying contains a powder of a compound of a rare earth element with a specific surface area of 30 m2/g or more as determined by a BET single-point method. The powder preferably has a volume of pores with a pore size of 3 to 20 nm of 0.08 cm3/g or more as determined by a gas absorption method. The powder also preferably has a crystallite diameter of 25 nm or less. The powder also preferably has a repose angle of from 10 to 60°. In the L*a*b* color system, the powder also preferably has a value L of 85 or more, a value a of from ?0.7 to 0.7, and a value b of from ?1 to 2.5.

Abstract: A powder for coating or sintering has a peak assigned to cubic Y3Al5O12 and a peak assigned to orthorhombic YAlO3 exhibited in X-ray diffractometry, and the intensity ratio of the peak assigned to the (112) plane of the orthorhombic YAlO3 to the peak assigned to the (420) plane of the cubic Y3Al5O12 is at least 0.01 and less than 1. Alternatively, a powder for coating or sintering includes a composite oxide of yttrium and aluminum, and the volume of pores with a pore size of from 0.1 to 1 ?m of the powder is at least 0.16 mL/g. It is preferable that, in X-ray diffractometry using CuK? radiation with a scan range of 2?=20° to 60°, a peak assigned to the cubic Y3Al5O12 is a peak that shows the highest peak intensity.
