Product Description

U shape of high quality of molybdenum disilicide heater 

1.Molybdenum disilicide(MoSi2) heating element is a resistance generate-heating component made from MoSi2 or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2 glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800°C during oxidizing atmosphere. And the applicable temperature is 500-1700°C.
2.Resistance property
The resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, generally the element resistance doesn't change with the service time changing. So the old and new elements can be mixed used.
 
3.Phiscal property
 

Volume Density	5.5g/cm3	Porosity	7.40%
Bending Strength	15-25kg/cm3	Water absorption	1.20%
Vickers Hardness	(HV)570kg/mm2	Heating Elongation Rate	4%

 
4.Chemistry property
 
MoSi2 heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700°C,the MoSi2 heating element must not be used in the temperature between 400°C and 700°C for a long time; otherwise the element will be cremated under the strong oxidizing function in the low temperature.
