Product Overview

Molybdenum disilicide (MoSi2) heating element is a resistance generate-heating component made from MoSi2 or the basic material. MoSi2 heaters operating temperature usually range from 1300°C to 1750°C, which mainly used in the industries of metallurgy, glass, ceramic refractory, crystal electronic device, industrial furnace manufacture, etc. MoSi2 heaters are essential ideal heating element when heated products need to be sintered in the high temperature.

Notice to furnace operation

To avoid high current surges which may cause damage to MoSi2 heaters, the recommend starting procedure as following:
0C-200C 3°C/min
200C-500C 5°C/min
500C-1000C 8°C/min
1000C-1600C 10°C/min
1600C-1750C 3°C/min

Warning: The MoSi2 rod 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 400°C and 700°C for a long time, otherwise the element will be cremated under the strong oxidizing function in the low temperature
