Moly Disilicide Heating Elements Description
Moly Disilicide Heating Elements is a kind of resistance heating element basically made of pure molybdenum Disilicide. In oxidizing
atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi 2 element owing to the high temperature combustion, which prevents Mosi 2 from continuously oxidizing.

- 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.
