Abstract

A spraying material comprising a rare earth (R), aluminum and oxygen, the spraying material being a powder and comprising a crystalline phase of a rare earth (R) aluminum monoclinic (RAlO) and a crystalline phase of a rare earth oxide (RO), with respect to diffraction peaks detected within a diffraction angle 2θ range from 10° to 70° by a X-ray diffraction method using the characteristic X-ray of Cu-Kα, the spraying material having diffraction peaks attributed to the rare earth oxide (RO) and diffraction peaks attributed to the rare earth (R) aluminum monoclinic (RAlO), and an intensity ratio I(R)/I(RAL) of an integral intensity I(R) of the maximum diffraction peak attributed to the rare earth oxide (RO) to an integral intensity I(RAL) of the maximum diffraction peak attributed to the rare earth aluminum monoclinic (RAlO) being at least 1.
