Molybdenum disilicide heating elements (MoSi2) is a molybdenum disilicide heating element base made of high temperature oxidizing atmosphere, the surface of the glass, generating a dense layer of shiny quartz (SiO2) glass membrane, can no longer protects the silicon oxide molybdenum rod, molybdenum silicon rod element therefore has a unique high temperature oxidation resistance. In an oxidizing atmosphere, the element maximum use temperature of 1800 ℃, according to user needs can be made rod, U-shaped, W, U-right angle shape.
