Brief introduction of molybdenum silicide

2022-03-31

Molybdenum silicide, also known as molybdenum silicide with molecular weight of 154.13, is a kind of molybdenum silicide compound.

Because the radii of the two atoms have little difference and the electronegativity is relatively close, it has similar characteristics to metals and ceramics. The melting point is up to 2030 ℃. It has conductivity and can form a silica passivation layer on the surface to prevent further oxidation at high temperature. Its appearance is gray metallic and is from its square shape α It also has hexagonal shape, but it is unstable Β Modified crystal structure. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid.

Application of molybdenum silicide

Molybdenum disilicide is used in high temperature oxidation resistant coating materials, electric heating elements, integrated electrode films, structural materials, composite materials, reinforcing materials, wear-resistant materials, structural ceramic connecting materials and other fields.

Application fields of molybdenum silicide

1. Energy and chemical industry: electric heating elements, high-temperature heat exchangers of atomic reactors, gas burners, high-temperature thermocouples and their protective tubes, melting containers and crucibles (used for smelting sodium, lithium, lead, bismuth, tin and other metals).

2. Microelectronic industry: MoSi2 and other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidate materials for gate and interconnection films of large-scale integrated circuits.

3. Aerospace industry: as a high-temperature antioxidant coating, it has been widely and deeply studied and applied. In particular, materials used as turbine engine components, such as blades, impellers, burners, tail nozzles and sealing devices.

4. Automobile industry: turbocharger rotor, valve body, spark plug and engine parts of automobile turbine engine.
