Chemistry Property of MoSi2 Heating Elements
Mosi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700 °C, the SiO2 protecting film is formed again when the element continues to be used. The Mosi2 heating element must not be used in the temperature between 400°C and 700°C, otherwise the element will be creamed under the strong oxidizing function in the low temperature.
