1700/1800.C MoSi2 Heating Element
Mosi2 heating elements is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of MoSi2 element owing to the high temperature combustion, which prevent MoSi2 from continuously oxidizing. In oxidizing atmosphere, its Max temperature can reach 1800.C, and its applicable temperature is 700-1700.C(can’t be used in 400-700.C for a long time, otherwise, it will be powdered and damaged due to strong oxidizing action in low temperature).
It can be widely used in such applications as heating elements of sintering and heat treatment of ceramics, magnet, glass, metallurgy, refactory,etc.
The most common shape is U. It is widely used for industrial and laboratory furnaces.
|Volume Density||Bending Strength||Vickers Hardness|| Porosity
|Water Absorption||Heating Elongation Rate|
|5.5~5.6 g/cm3||15-25 kg/cm3||(HV)570kg/mm2||7.4%||1.2%||4%|
Under high temperature, MoSi2 heating element will form one SiO2 protective film on the surface, which prevents the element from oxidizing continuously. When the element temperature is over 1700 °C, the film becomes melting. It’s not suitable for long time use in the temperature range of 400-700°C, otherwise, the element will be powdering for the strong oxidation under low temperature.
The resistivity of MoSi2 heating element rapidly rises as the temperature rises. Under normal operating conditions, the element resistance generally doesn’t change with the service life, so the old elements can be used with the new elements together.
Choosing MoSi2 heating element surface load based on furnace structure, temperature as well as atmosphere, is the key of optimizing element service life
