1) Description
1. General Description: 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 1800C during oxidizing atmosphere.
2. Specific Properties: low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc.
3. Characteristics: MoSi2 heating element can usually make use of furnace temperature from 1300C to 1800C. It is used to the highest temperature up to 1800C during oxidizing atmosphere.
4. Application: It is extensively used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc.. It is an essential ideal element when the products are sintering in the high temperature.
2) Products specification:
In addition to MoSi2 elements in standard shapes and sizes we provide special designed MoSi2 elements according to customer needs, enabling an optimized element design for each particular application.

2. Chemistry Character
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. During the oxidizing process, the SiO2 protecting film is formed again when the element continues to be used. The MoSi2 heating element must not be used in the temperature between 400C and 700C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature.
