Warning

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. During the oxidizing process, 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 ^oC and 700 ^oC for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.
