What is Molybdenum Disilicide Used For?

Molybdenum diilicide MoSi2 a form of intermediate phase has the highest silicon content within Mo-Si binaural alloy. This is a Dalton intermetallic compound. The material is high in temperature and exhibits excellent performance. It has both the characteristics of ceramic and metal. MoSi2 exhibits good resistance to high temperatures, with a oxidation resistant temperature as high at 1600. It is very similar to SiC. It exhibits moderate density (6.24g/cm3). Low thermal expansion coefficient (8.1×10-6 K-1), high electrothermal conductivity (good electrothermal conductivity), and ceramic-like hardness, brittleness, and lower brittle-ductile temperature (1000). It has a soft plasticity that is metal-like and exceeds 1000. MoSi2 is used primarily as a heating element, integrated circuit and high temperature oxidation resist coating.

MoSi2, silicon and molybdenum are bound by metal bonds. In MoSi2, silicon and silica are connected via covalent bonds. Molybdenum is a gray, tetragonal crystal. It cannot be dissolved in all mineral acids except aqua regia, but it can be dissolved in a mix of hydrofluoric acid and nitric acid. It can be used to heat in high-temperature oxidation environments (1700) due to its excellent oxidation resistance.

What’s Molybdenum Disilicide used for?

In high temperature antioxidation coatings, electric heating elements and integrated electrode films, molybdenum diicides are used. Specifically:

Chemical industry for energy: high temperature heat exchangers in atomic reactor devices and gas burners. High temperature thermocouples with their protective tubes. Melting vessel crucibles are used to melt metals such as sodium, lithium, lead and bismuth.

Industries in microelectronics include MoSi2 (and other refractory silicide Ti5Si3), WSi2, TaSi2 which are key candidates for interconnect films and gates of large-scale integrated Circuits.

High temperature anti-oxidation coatings for aerospace industry. This material was the subject of extensive research. 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 are the MoSi2 restrictions?

MoSi2 is very soft at low temperatures (below 1000°C), which indicates that it will become plastic when heated up to higher temperatures.

The material is also susceptible to creeping at temperatures higher than 1200°C.
