MOLYBDENUM CRUCIBLE FOR METAL EVAPORATION AND MANUFACTURING METHOD AND USE METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a molybdenum crucible for metal evaporation hard to react with a molten metal at high temperature.SOLUTION: A molybdenum crucible for metal evaporation is subjected to carbonization in a state where the inner wall surface of a crucible substrate 1-a composed of molybdenum has at least approximate 800°C or more, and thus a surface layer becomes molybdenum carbide 1-b. Since the contact angles of the surface layer of the molybdenum carbide and many molten metals 5 is beyond 100 degrees at 1000°C and wettability relatively becomes worse, react with the molten metal can be suppressed.
