A. Molybdenum Disilicide Heating Elements Introduction:
Silicon molybdenum rod resistive electric heating element, based on molybdenum disilicide, resistant to high temperature and oxidation. When used in a high-temperature oxidizing atmosphere, a layer of bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon-molybdenum rod from oxidation, and the silicon-molybdenum rod element has unique high-temperature oxidation resistance.
Mosi2 heating element consists of hot zone and cold zone, the welding point is beautiful ,smoothly, without bump
It should be pointed out that element cannot be used for rather long time in 500-1700°C, or it will be powdered owing to the strong oxidizing action in low temperature.
