mosi2 heater

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.

Having the same mechanical character as other ceramic products ,MoSi2 heating elements belong to the brittleness material so that they are easy to rupture at the normal temperature ,which brings some difficulty to transport and install,but it may be avoided if they were installed and used correctly.

Physical and chemical properties of elements 

Volume density	5.5~5.6kg/cm3	Bend strength	515~25kg/cm2
Vickers-hadness	(HV)570kg/mm2	Porosity rate	7.4%
Water absortion	1.2%	Hot extensiblity	4%

2.Chemical propertyOxygen-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.Physical and chemical properties of elements
