Corrosion-resistant member
A corrosion-resistant member may include alumina ceramics containing α-alumina and anorthite. The alumina ceramics may contain 0.4% by mass or more of Ca and Si in total in terms of CaO and SiO2, respectively, and a mass ratio of CaO/SiO2 may fall within a range of 0.5 to 2. Moreover, a ratio B/A of X-ray diffraction peak intensity B for (004) plane of the anorthite to X-ray diffraction peak intensity A for (104) plane of the α-alumina in a surface of the alumina ceramics, may be 0.01 or more.
