Molybdenum Disilicide (MOSI2) Heating Element

Molybdenum Disilicide (MOSI2) Heating Element

Molybdenum Disilicide Heating Element Type MoSi2 is an electric element principally containing molybdenum disilicide for use in industrial and laboratory furnaces. Elements fabricated of this unique material support high power densities on their surface.

Made of molybdenum disilicide based cermets MoSi2 heating elements withstand oxidation at very high temperatures. Their surface is protected by of a thin layer of silica glass that forms when they are exposed to oxygen at elevated temperatures. Although the base cermet is consumed in the formation of the silica ""skin"" the rate of decomposition is minimal. They provide long performance at elevated temperatures while delivering high power.

MoSi2 heating elements operate at the highest temperatures and give longest life in oxidizing atmospheres. They can operate in other atmospheres but have reduced maximum temperatures.

Typical applications:

  • Heating source in furnaces and industrial process equipment operating to 1800°C (3272°F)
  • Elements in production, laboratory and research furnaces for annealing, heat treating, forging, ceramic and metal sintering, glass and metal melting, holding & refining, etc

For highest temperature and power performance plus longest life MoSi2 Heating Elements should be installed in a free hanging manner.

At low temperatures MoSi2 heating elements are brittle and should be handled with care. At temperatures above 1200°C they become ductile and sag under their own weight.

Working temperature up to 1800°C.
