2.What's the Molybdenum disilicide(MoSi2) heating element?
Molybdenum disilicide (MoSi2) heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi2 element owing to the high temperature combustion, which prevent Mosi2 from contiously oxidizing. In oxidizing atmosphere, its max temperature can reach 1800°C, and the applicable temperature is between 500-1700°C.
3.Applications:
It can be widely used in such applications assintering and heating elements of ceramics, magnet, glass, metallurgy, refractory, etc.

2) Chemical Properties
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 contiously oxidizing. 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.

7.Notice for using
It should be pointed out that element cannot be used for rather long time in 500-1700°C, or it will be powdered owing to the strong oxidizing action in low temperature
