    摘要： 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.

    摘要： A thermal spray material comprising granules containing a rare earth oxyfluoride has a particle diameter of 1 to 150 μm at a cumulative volume of 50 vol % before ultrasonic dispersion and 10 μm or smaller after ultrasonic dispersion at 300 W for 15 minutes as determined by laser diffraction/scattering particle size distribution analysis. The particle diameter after ultrasonic dispersion is one-third or less of that before ultrasonic dispersion. The thermal spray material has an average aspect ratio of 2.0 or lower and a compressibility of 30% or less. When the granules further contain a rare earth fluoride, upon being analyzed by X-ray diffractometry using Cu-Kα or Cu-Kα1 radiation, S1/S2 is preferably ≧0.10. S1=intensity of the maximum peak assigned to the rare earth oxyfluoride. S2=intensity of the maximum peak assigned to the rare earth fluoride, both observed in a 2θ angle range of 20° to 40°.

    摘要： The present invention is a sintering material including a granule, the sintering material having an apparent tap density of 1.0 to 2.5 g/cm3, a 50% cumulative volume particle diameter (D50N) of 10 to 100 μm as measured before ultrasonication by laser diffraction/scattering particle size distribution analysis, a 50% cumulative volume particle diameter (D50D) of 0.1 to 1.5 μm as measured after ultrasonication at 300 W for 15 minutes by laser diffraction/scattering particle size distribution analysis, and an X-ray diffraction pattern in which the maximum peak observed in the 2θ angle range of from 20° to 40° is assigned to a rare earth oxyfluoride of the form LnOF when analyzed by X-ray diffractometry using Cu—Kα or Cu—Kα1 rays.
