Product Description
Silicon molybdenum rod resistive heating element is a kind of resistance heating element with high temperature resistance and oxidation resistance made of molybdenum disilicide. When used in high-temperature oxidizing atmosphere, like other Si based high-temperature resistant materials, MoSi2 surface will rapidly form a bright and dense quartz (SiO2) glass film under high temperature and oxygen atmosphere, which can protect the inner layer of silicon molybdenum rod from further oxidation. Therefore, silicon molybdenum rod elements have unique high-temperature oxidation resistance.

Precautions for silicon molybdenum rod
1. The silicon molybdenum rod heating element should not be used within the temperature range of 400 ° C to 700 ° C, because under such unfavorable conditions, the element will undergo low-temperature oxidation and damage the element. 
2. The silicon molybdenum rod heating element is suitable for use in air and neutral atmosphere. Reducing atmosphere such as hydrogen will damage the protective layer, and chlorine and sulfur vapor will directly damage the element.
