|1. (WO2018124024) CORROSION-RESISTANT MEMBER|
The corrosion-resistant member according to the present disclosure comprises an alumina ceramic containing α-alumina (α-Al2O3) and anorthite (CaAl2Si2O8). The alumina ceramic contains a total of 0.4 mass% or more of Ca and Si in terms of CaO and SiO2, respectively, and the mass ratio of CaO/SiO2 is within the range of 0.5-2. In addition, the ratio B/A of a peak strength B of X-ray diffraction on the (004)-plane of the anorthite to a peak strength A of X-ray diffraction on the (104)-plane of the α-alumina, is 0.01 or more at the surface of the alumina ceramic.
