Overview
Molybdenum properties are unique which makes it desirable for use in a number of manufacturing industries. For example, with its high melting point, 2620°C, molybdenum can work as a load bearing material in industrial furnaces at temperatures ranging 1600°C and up to 2000 °C for certain other applications. As the metal readily oxidizes above 400° C in air, a protective atmosphere like a vacuum, hydrogen-reducing, or inert gas is required for high-temperature operations. In addition to its high-temperature strength, molybdenum exhibits excellent thermal and electrical conductivity and low vapor pressure at elevated temperatures. Such properties, make molybdenum particularly useful metal injection molding, hot isostatic pressing, vacuum, nuclear fuel sintering, and glass melt furnaces.
