What is Molybdenum disilicide used for?

Molybdenum disilicide overview

Molybdenum disilicide is the silicon compound of molybdenum, also known as molybdenum silicide. Since the radii of the two atoms are not much different, the electronegativities are relatively close, and they have similar properties to metals and ceramics. The melting point is as high as 2030 ℃, and it is conductive. At high temperature, a passivation layer can form silicon dioxide on the surface to prevent further oxidation. Appearance is gray metallic color, derived from its tetragonal α-type crystal structure, and also has a hexagonal but unstable β-modified crystal structure, insoluble in most acids, but soluble in nitric acid and hydrofluoric acid.

What are the limitations of MoSi2?

MoSi2 exhibits low toughness below 1000 °C, which means that the material is very brittle at room temperature and only becomes plastic at higher temperatures.

It exhibits poor creep resistance above 1200 °C.

Application of molybdenum disilicide

Molybdenum disilicide is used in high temperature anti-oxidation coating materials, electric heating elements, integrated electrode films, structural materials, composite material reinforcements, wear-resistant materials, and structural ceramic connecting materials. Distributed in the following industries

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

2) Microelectronics industry: MoSi2 and some other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidates for large-scale integrated circuit gate and interconnect films.

3) Aerospace industry: As a high temperature anti-oxidation coating material, it has been widely and deeply researched and applied. Especially as materials for turbine engine components such as blades, impellers, combustors, nozzles and seals.

4) Automobile industry: turbocharger rotors, valve bodies, spark plugs and engine parts for automobiles.

Molybdenum disilicide can also be used in the heating elements of ceramic heaters. Molybdenum silicide maintains good oxidation resistance by forming a protective film on the surface even at high temperatures of 1700°C. Molybdenum silicide is used as a structural material for high temperature components in aerospace and automotive gas turbines, gas combustion nozzles and high temperature filters.
