Molybdenum Siicide MoSi2 MoPowder:


An intermetallic compound.

silicide molybdenum

This is a refractory clay, which is mostly used to heat elements. It is medium in density and has a melting temperature of 2030°C. This makes it very electrically conductive. To protect the material from further oxidation, it forms an insulating layer of silica at higher temperatures. Thermal stability


Because of their thermal stability and high radiation, such materials can also be used as thermal shields against the atmosphere.

MoSi2 powder

This is a gray metal with a square crystal structure. It is also known as a-modified. It’s insoluble in all acids. However, it dissolves in hydrofluoric or nitric.


molybdenum disilicide MOSi2

Although it has an excellent resistance to oxidation, and a high Young’s modulus at temperatures over 1000°C, it becomes brittle when temperatures drop below this level. At 1200°C or higher, creep resistance is lost. However, these properties are restricted to the structural material of the materials. They can however be modified using a composite made with another material.

Molybdenum Disilicide (MoSi2)

This material is promising for use in high-temperature structural applications. The material is high in melting points (2030 C) and has moderate densities (6.24 g/cm3). Unfortunately, its low toughness at low temperatures as well as high creep rates at elevated temperature have prevented commercialization of this material for structural purposes. A lot has been done to improve the product.

MoSi2 Composites

As alternatives to pure

disilicide molybdenum

These are for aggressive, oxidizing environments.

Molybdenum-based heating elements using disilicides

These silicas have been widely used in high temperature furnaces. Microelectronic applications require silicas with low electrical resistance. This is in addition to their excellent thermal stability and electron-migration resistance. To receive the latest information, please send us an inquiry

Is powder produced?

Sintering is used to make Molybdenum Disilicide and MoSi2-based material. The plasma spraying process can produce both dense monoliths as well as composite forms. Because of its fast cooling, plasma spraying can result in a significant amount of bMoSi2 in the material.


Molybdenum Silicide



The temperature range of Molybdenum Disilicide Heating Elements can reach 1800C. They are suitable for use in both laboratory and industrial environments. Molybdenum is used as a Contact Material in microelectronics.

Heating element

MoSi2 is an electroconductive silica that exhibits an oxidation capability due to the presence of a silica-rich layer at its surface.

While the MoSi2 top element is capable of operating at temperatures as high as 1800°C, it’s very fragile and can suffer from creep. These elements have advantages in that they are resistant to high electric loads and can withstand aging. They can be used in an oxygen-rich, air or oxygen-rich environment to exhibit antioxidant properties.

You can use them with ammonia or nitrogen as well as hydrogen. The operating temperature can also be reduced due to the failures of protective oxide layers.

MoSi2 elements can be bent or made straight in any shape. These elements are mostly used in the ceramics, glass, steel and electronics industries.

High-temperature structures

MoSi2’s high-temperature elasticity and remarkable strength make it an attractive material for gas turbine engines. Researchers are working hard to enhance low-temperature and high temperature creep resistance. Unfortunately, composites aren’t commercially made with all the desirable features.
