MoSi2 heating elements physics and chemistry characters:

5.5 g/cm3 15-25 kg/cm3 (HV)570kg/mm2 7.4% 1.2% 4%
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.
Electric Character
1) Resistance property
The resistivity of element rapidly rises as the temperature rises, under normal operating conditions, generally the element resistance doesn't change with the service time changing. So the old and new elements can be mixed used.
MoSi2 Heating Element's installation:
The brittleness of MoSi2 heating element is relative more under the usual temperature, it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector cant be screwed too tightly. When temperature of the element is going up, please twist it tightly again, so the element is not easily broken.
(our suggestion: please choose the specialize power connector provided by our co***ny)
The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top cant be over 300C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than 50mm between the low end of connector and the |
