Smelting Furnace Molybdenum Disilicide Heating Element 1700 1800 Degree
Molybdenum Disilicide Heating Element Introduction
Molybdenum Disilicide Heating Element is a kind of resistance heating element basically made of high pure 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, MoSi2 heating element can usually make use of furnace temperature from 1300 to 1850 degree.
Mosi2 Heater Elements Feature
- MoSi2 heating elements is a kind of resistance heating element made from Molybdenum Disilicide.
- Working temperature of MoSi2 heating element is 1300C to 1800C.
- Widely used in the industries of metallurgy, glass, ceramic refractory,crystal electronic device, industrial furnace manufacture, etc
