What is Molybdenum Disilicide Used For?

Molybdenum diilicide MoSi2 a type intermediate phase has the highest silicon level in Mo-Si binaural alloy system. It is a Dalton intermetallic compound with fixed structure. It has both the characteristics of ceramic and metal, and is an excellent material for high temperatures. MoSi2 exhibits good resistance to oxidation at high temperature. The oxidation temperature can reach 1600. This is very similar to SiC. It has a moderate density (6.24g/cm3). It also has a low thermal extension coefficient (8.1×10-6 K-1), high electrothermal conductivity, good ceramic-like hardness, and brittleness at temperatures below the higher, brittle-ductile, transition temperature (1000). It exhibits a soft plasticity that is metal-like above 1000. MoSi2 can be used as a heating element or integrated circuit. It also has high temperature oxidation resistance coatings and high-temperature structural material.

MoSi2 contains silicon and molybdenum bonded with metal bonds. In MoSi2, silicon and silicon can be connected by covalent bond. Molybdenum disilicide, which is a gray, tetragonal crystal, is also present. It is insoluble with most mineral acids (including aqua regia), but it can be dissolved by a mixture of hydrofluoric and nitric acids. It is resistant to high temperatures and can therefore be used as a heating element in an oxidation environment at high temperatures (1700).

What’s Molybdenum Disilicide used for?

Molybdenum diicide is used for high temperature antioxidation coating materials, electric heating element elements, structural materials, reinforcers and wear-resistant material, bonding materials of structural ceramics, and integrated electrode films. Specifically:

Energy chemical industry: Electric heating elements, high heat exchangers of nuclear reactor devices, gas burners. High temperature thermocouples with their protective tubes. Melting vessel crucibles (for melting tin, sodium, lead, bismuth, and lithium).

Industries in microelectronics: MoSi2 is an important candidate material for large-scale interconnect and gate films for large-scale integrated Circuits.

Aerospace industry: The application and research into high-temperature antioxidation coating materials has been extensive. It is used as a material for components of turbine engines such as blades. impellers. burners. tail nozzles. sealing devices.

Automotive industry: engine parts, turbochargers, valve bodies and spark plugs.

What restrictions does MoSi2 impose?

MoSi2 is very soft at temperatures below 1000°C. This means it will become plastic only at higher temperatures.

It is also susceptible to creeping at temperatures exceeding 1200 degrees Celsius.
