Molybdenum disilicide is an inorganic compound with the chemical formula MoSi2, which is a gray metallic solid. Molybdenum disilicide is insoluble in most acids, but soluble in nitric acid and hydrofluoric acid.

Molybdenum Disilicide Powder Properties

MoSi2 is an intermediate phase with the highest silicon content in the Mo-Si binary alloy system, and it is a Dalton-type intermetallic compound with a fixed composition. Molybdenum disilicide has the dual characteristics of metal and ceramics, and is a high-temperature material with excellent performance.
Molybdenum disilicide has good high-temperature oxidation resistance, and the oxidation resistance temperature is as high as 1600; molybdenum disilicide has a relatively low coefficient of thermal expansion (8.1×10-6K-1); it has good electrical and thermal conductivity.

Molybdenum disilicide is conductive and can form a passivation layer of silicon dioxide on the surface at high temperatures to prevent further oxidation. MoSi2 has good high-temperature oxidation resistance and can be used as a heating element working in high-temperature (<1700degC) oxidizing atmosphere.

Molybdenum Disilicide Powder Applications

Molybdenum disilicide is used in the fields of high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode films, structural materials, composite material reinforcements, wear-resistant materials, and structural ceramic connection materials, and is distributed in the following industries:

1) Energy and chemical industry: MoSi2 is used as electric heating element, high temperature heat exchanger of atomic reactor device, gas burner, high temperature thermocouple and its protection tube, smelting vessel crucible (used for smelting sodium, lithium, lead, bismuth, tin And other metals).

2) Microelectronics industry: MoSi2 and other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidate materials for large-scale integrated circuit gates and interconnection lines.

3) Aerospace industry: Molybdenum disilicide has been widely and deeply researched and applied as a high-temperature anti-oxidation coating material, especially as a material for turbine engine components, such as blades, impellers, combustors, nozzles and sealing devices.

4) Automobile industry: Molybdenum disilicide is used in turbocharger rotors, valve bodies, spark plugs and engine parts of automobiles.
