Product 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. According to your request, our company can produce the products of Pole, "U", "W" and "U"-right angle shapes, etc.
MoSi2 heating elements can usually make use of furnace temperature from 1300C to 1800C. 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.
Application
It can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory, etc.
Advantages
Mosi2 heating element can quickly form a thin and adhesive anti-oxidizing layer of quartz glass(Sio2), under the high temperature oxidizing condition. If the protective layer was damaged, the element can reform a new one, so Mosi2 heating element has a very good anti-oxidation properties, it also means that the heating element can be used on operation for a much longer time than the traditional one.
The resistivity of the Mosi2 heating element is not changing with the time, so a new one can be installed without effecting the old one, this can result of huge saving in furnace maintenance fee sand time as well, increase the working efficiency, this is the key point of Mosi2 heating element being a better material and being widely used.

Chemical Properties
Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz (SiO2) protective film is formed on the surface of element owing to the high-temperature combustion, which prevent Mosi from continuously oxidizing. When the element temperature is higher than 1700ºC, the SiO2 protective film will be fused because fused because its fusing point is 1710ºC and the SiO2 is fused into molten drops owing to the action of its surface extension, which cause losing its protective ability. In the oxidizing atmosphere, when the element is contiguously used, the protective film forms again.
It should be pointed out that element cannot be used for rather long time in 400-700ºC. Otherwise, it will be powdered owing to the strong oxidizing action in low temperature.
