About Molybdenum Silicide:
Molybdenum disilicide (MoSi2, or molybdenum silicide) with CAS 12136-78-6, an intermetallic compound, a silicide of molybdenum, is a refractory ceramic with primary use in heating elements. It has moderate density, melting point 2030 °C, and is electrically conductive. At high temperatures it forms a passivation layer of silicon dioxide, protecting it from further oxidation. The thermal stability of MoSi2 alongside its high emissivity make this material, alongside WSi2 attractive for applications as a high emissivity coatings in heat shields for atmospheric entry. MoSi2 is a gray metallic-looking material with tetragonal crystal structure (alpha-modification); its beta-modification is hexagonal and unstable.

Application of Molybdenum Silicide:
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. While the elements are brittle, they can operate at high power without aging, and their electrical resistivity does not increase with operation time. Their maximum operating temperature has to be lowered in atmospheres with low oxygen content due to breakdown of the passivation layer.
Other ceramic materials used for heating elements are e.g. silicon carbide, barium titanate, and lead titanate composite materials.
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.
Storage Condition of Molybdenum Silicide Powder:
Damp reunion will affect Molybdenum Silicide powder dispersion performance and using effects, therefore,Molybdenum Silicide Powder should be sealed in vacuum packing and stored in cool and dry room, the Molybdenum Silicide Powder can not be exposure to air. In addition, the Molybdenum Silicide powder should be avoided under stress.
