Mosi2 heating tube element

Key Attributes.

Mosi2 heating tube element is a kind of resistance heating element basically made of high purely Molybdenum Disilicide. In oxidizing atmosphere, on the surface of MoSi2 element owing to the high temperature combustion a layer of compact quartz protective film is formed to prevent MoSi2 from continuously oxidizing. In oxidizing atmosphere, its Max temperature can reach 1800°C. The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, generally the element resistance doesn't change with the service time changing so the old and new elements can be used mixed. The key factor to the optimum service life of the element is to select the surface load of the element correctly according to the furnace construction, atmosphere and temperature
