General Description:


Electric heating element is a kind of resistance heating element made from Molybdenum Disilicide.
It can be used in air and various gases environments. Working temperature of MoSi2 heating
element is 1300C to 1800C. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high temperature low distortion, easy installation and maintenance, excellent chemical stability, which has been widely used as heaters in high temperature furnaces and kilns of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture and chemical industry field.

Chemistry Character

MoSi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.


Following should be provided when ordering U Type MoSi2 Heating Elements:

  • Grade: 1700, 1800 or 1900
  • Diameter: D1/D2, in/in or mm/mm
  • Heated Length: Le*, in. or mm
  • Terminal length: Lu*, in. or mm
  • Shank Spacing: A*, in. or mm
  • Specify Le, Lu and A with the same units (e.g. all as in. or mm).

  1. Chemical Properties of Physical Properties of MoSi2 Heating Element

Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent Mosi2 from oxidizing more. When the element temperature is higher than 1700 °C, the film becomes melting. It’s not suitable for long time use in the temperature range of 400-700°C, otherwise, the element will be powdering for the strong oxidation under low temperature.
