Oxidation Resistance Metallurgy MoSi2 Heating Element
MoSi2 Heating Element General Description:
High Purity MoSi2 Heating Element 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 are U & W. They are widely used for industrial and laboratory furnaces.
Following should be provided when ordering U Type MoSi2 Heating Elements:
Examples:
U-Shape, Material Grade 1800, D1=3mm, D2=6mm, Le=140mm, Lu=125mm, A=25mm
Specify as: 1800 U-Shape, 3/6 x 140 x 125 x 25

Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent Mosi2 from oxidizing more. When the element temperature is higher than 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.
