W-shape 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. Its 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.
