General MoSi2
Heateris 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 compact 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 ***0C 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 be used in furnace
temperature from ***0C to ***0C. 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.

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 **0C and **0C for a long time, otherwise
the element will be cremated under the strong oxidizing function in
the low temperature.
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.
