Electric Resistance Furnace MoSi2 Heating Elements Anti Oxidation

Electric Resistance Furnace MoSi2 Heating Elements Anti Oxidation

MoSi2 Heating Elements is a resistance generate-heating component made from MoSi2 or the basic material. Above 900C temperature the surface will form a SiO2 protection film on its surface for preventing it continuing oxidized. The MoSi2 Heating Elements must not be used in the temperature 400-700C for a long time, otherwise the element will be cremated in the low temperature.

MoSi2 Heating Elements Feature

1. High temperature for various electric furnaces.
2. Long life combined with ease of replacing failed elements
3. Can be used continuously or intermittently
4. New and old elements can be connected in series
5. High power concentration may be applied

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.
