High Temp Molybdenum Disilicide Heating Elements
Molybdenum Disilicide Heating Elements Introduction:
Molybdenum Disilicide Heating Elements are a kind of resistance heating element made from Molybdenum Disilicide.
It can be used in air and various gases environments. Working temperature of MoSi2 heating
element is 1300C to 1800C. It has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high temperature low distortion, easy installation and maintenance, excellent chemical stability, which has been widely used as heaters in high temperature furnaces and kilns of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture and chemical industry field.

Advantage
- Because of the special technology, welding spot is fast and shock resistance, which dramatically reduced the damaged probability of welding spot by electric current, as well as transit and installation.
- High density of Spark MoSi2 Heating Elements increases its electrical conductivity. The characters of faster warming and power consumption low, which reduce production cost.
- Good appearance quality and tenacity, high mechanical strength.
- Adopt special technology, heaters come with compact protective layer, excellent performance in no-oxidizing atmosphere electric furnaces.
Note: For inquiry, it is better to provide a drawing of the element and specify the element diameters in millimeters. For example, an element with a (D1) diameter of 9 mm and a (D2) diameter of 18 mm is often referred to as a 9/18 element. Other dimensions may be specified in millimeters .
