mosi2 heater resistance heating element ,resisting oxidization in high temperature ,refractoy, extensively used ,excellent quali
MoSi2 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 hige 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,and itds applicable temperature is 500-1700°C.it can be widely used in such applications as sintering and heat treatment on ceramics,magnet,glass,metallurgy,refractory,etc.the commercial name of our MoSi2 heating elements is Yuhao MoSi2 Heating Elements.

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.
