Molybdenum Disilicide (MoSi2) Micron Powder
Molybdenum disilicide (MoSi2, or molybdenum silicide), an intermetallic compound, a silicide of molybdenum, is a refractory ceramic with primary use in heating elements. It has moderate density (6.26 g/cm3) , melting point 2030 °C, and is electrically conductive. Molybdenum disilicide micron powder has excellent friction, large active surface area, more adsorption capacity, high reactivity, catalytic properties. Molybdenum disilicide and MoSi2-based materials are usually made by sintering. Plasma spraying can be used for producing its dense monolithic and composite forms; material produced this way may contain a proportion of β-MoSi2 due to its rapid cooling. Molybdenum disilicide is used in microelectronics as a contact material. It is often used as a shunt over polysilicon lines to increase their conductivity and increase signal speed. It can be also used in lubricant, and composite applications and as a conductive filler. Moreover, molybdenum disilicide heating elements can be used for temperatures up to 1800 °C, in electric furnaces used in laboratory and production environment in production of glass, steel, electronics, ceramics, and in heat treatment of materials.
