Molybdenum Heating Elements

1. U shape mosi2 heaters is a kind of resistance heating element basically made of high pure Molybdenum.
2. In oxidizing atmosphere, its Max temperature can reach 1800 deg.C, and its applicable temperature is 500~1700
deg.C.
3. It can be widely used in such applications as sintering and heating treating of ceramic, magnet ,glass, metallurgy,
refractory and so on.

Quantity:
  • FOTMA
Molybdenum disilicide (MoSi2) heating element is a resistance generate-heating component madefrom MoSi2 or the basic material. It has unique effect for resisting oxidization in the hightemperature. It is used to the highest temperature up to 1800 degreesduring oxidizing  atmosphere.
1. Dia. 3,4,6,7,9,10,12,18,24
2. Temp: 1000-1800 celsius degrees
3. Used in the industries of metallurgy, magnetic materials, glass, ceramic refractory, crystal electronic device,industrial
    furnace manufacture, lab furnace,Laboratory furnace,industry furnace,glass furnace,ceramic furnace etc.
 
 
 

Chemical CharacterMoSi2 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.
