Description
What's the Molybdenum disilicide(MoSi2) heating element?
Molybdenum disilicide(MoSi2) heating element is one resistance heating component made from MoSi2 or as the basic material. When it's heated to high temperature under the oxidizing atmosphere, one dense MoSi2 film will be formed on its surface to protect the element against oxidizing further. Therefore, the element has unique anti-oxidation property under high temperature atmosphere. The highest temperature can reach 1800°C, the applicable temperature is between 500-1700°C.

2. Chemistry Property
Under high temperature, MoSi2 Molybdenum disilicide heating element will form one SiO2 protective film on the surface, which prevents the element from oxidizing continuously. When the element temperature is over 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.
