MoSi2 Heating element
kejia molybdenum disilicide MoSi2 heating elements can quickly form a thin and adhesive anti-oxidizing layer of quartz glass (SiO2), under the high temperature oxidizing condition. If the protective layer was damaged, the element can reform a new one, so MoSi2 Heater Molybdenum Disilicide Heating Elements have a very good anti-oxidation properties, it also means that the heating element can be used on operation for a much longer time than the traditional one.It is used to the highest temperature up to 1850C during oxidizing atmosphere.
