    摘要: A corrosion resistant member to be exposed to a halogen-containing gas atmosphere or a halogen-containing gas plasma atmosphere, comprising a substrate and a plurality of layers deposited thereon including a layer of rare earth fluoride providing the outermost surface and a layer of rare earth oxide having a porosity of less than 5% underlying the rare earth fluoride layer.

    摘要: By using a rare earth metal having a minimal content of impurity metal element, machining it into a member and cleaning with an organic acid-base capping agent, there is obtained a rare earth metal member composed entirely of a rare earth metal and containing not more than 100 ppm of impurity metal element in a sub-surface zone, which member is characterized by a high surface purity, a large grain size, minimized grain boundaries, and improved halogen resistance or corrosion resistance.
