MoSi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, on the surface of MoSi2 element owing to the high temperature combustion a layer of compact quartz protective film is formed to prevent MoSi2 from continuously oxidizing. Therefore, molybdenum disilicide elements have unique high-temperature oxidation resistance. In oxidizing atmosphere, its Max temperature can reach 1800°C, and its applicable temperature is 500-1700°C. It can be widely used in such applications as sintering and heat treatment on ceramics, magnet, glass, metallurgy, refractory, etc.

MoSi2 heating element’s resistance does not change with use, in other words, that is not aging, so you can mix old and new components.

Oxygen-resistance under high temperature: In oxidizing atmosphere, on the surface of element owing to the high-temperature combustion a layer of compact quartz (SiO2) protective film is formed to prevent MoSi2 from continuously oxidizing. When the element temperature is higher than 1700°C, the SiO2 protective film, whose fusing point is 1710°C, is fused, and the SiO2 is fused into molten drops owing to the action of its surface extension, so that loses its protective ability. In the oxidizing atmosphere, when the element is continuously used, again the protective film forms.

It should be pointed out that element cannot be used for rather long time in 400-700°C,otherwise it will be powdered owing to the strong oxidizing action in low temperature.
