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 can’t 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 company)
The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top can’t 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 upside of the ceramic brick. The Dia.6 element can’t be used of 170A for a long time. The Dia.9 element can’t be used of 300A for a long time.
Molybdenum disilicide (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 element 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.

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.
To avoid high current surges which may cause damage to MoSi2 heating elements, the recommend starting procedure as following:
| Small Furnace (Power 100KW) | Big Furnace (Power 100KW-500KW) | ||
|---|---|---|---|
| Furnace Temperature ℃ | Voltage | Furnace Temperature ℃ | Voltage |
| 20-150 | 1/3 | 20-300 | 1/3 |
| 150-500 | 2/3 | 300-700 | 2/3 |
