Product Description

Mosi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi2 element owing to the high-temperature combustion, which prevent Mosi2 from continuously oxidizing. In oxidizing atmosphere, its max temperature can reach 1800ºC, and its applicable temperature is 500-1700ºC. According to shape , it can be divide into "pole " "U" "W". Special shape such as right angle shape and bend angle shape can be produced according to customer's request.


 

Application

 

Silicon molybdenum rod electric heating element products are widely used in metallurgy, Research and production of steelmaking, glass, ceramics, refractory materials, crystals, electronic components, and semiconductor materials manufacturing and other fields, especially for high-performance precision ceramics, high-grade intraocular lenses, precision structural cermets Production of porcelain, glass fiber, optical fiber and high-grade alloy steel.

 

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.
