1.Description of MoSi2 heating element u type 

MoSi2 heating rod is a kind of resistance heating element basically made of high

pure Molybdenum Disilicide. In oxidizing atmosphere,its Max temperature can reach

1800°C, and its applicable temperature is 500-1700C. It can be widely used in such

applications as sintering and heat treatment on ceramics, magnet, glass, metallurgy,

refractory, etc.  

Max. temperature:1700C, 1800C

Shape: I, U,UL,W,WL,Irregular

Diameter:3/6, 4/9, 6/12, 9/18,12/24mm

Special request from customers is welcome

4.Chemical property of MoSi2 heating element u type

Oxygen-resistance under high temperature:

In oxidizing atmosphere, on the surface of element owing to the high-temperature

combustion a layer of compact quartz (SiO2) protective film is formed to prevent

MoSi2 from continuously oxidizing.

When the element temperature is higher than 1700°C, the SiO2 protective film,

whose fusing point is 1710°C, is fused, and the SiO2 is fused into molten drops

owing to the action of its surface extension, so that loses its protective ability.

In the oxidizing atmosphere, when the element is continuously used, again the

protective film forms.
It should be pointed out that element cannot be used for rather long time in

400-700°C,otherwise it will be powdered owing to the strong oxidizing action

in low temperature.
