W-L type mosi2 heating element

MoSi2 heating element is a basis with molybdenum resistance heating elements. The sintering molybdenum products in high temperature oxidation atmosphere, the surface heat to generate a pre-pressing quartz glass, it can keep the membrane products, no longer oxidation. Therefore molybdenum elements of unique oxidation stability. In the next highest temperature oxidation atmosphere for 17 degrees Celsius (no more than quartz melting 1713 degrees Celsius).
MoSi2 heating element with use and resistance changes, also is not aging, so old and new components can be mixed use.
MoSi2 heating element of mechanical properties and other ceramic products at room temperature, easy to be broken, brittle material belongs to transport and install it brings certain difficulties. But if installed and used correctly can be avoided.

Chemical Properties

Oxidation stability, high temperature oxidation atmosphere: under the firing surface, silicon molybdenum rods one pre-pressing quartz layer to prevent the oxidation of MoSi2 continue. When more than 1700 degrees Celsius temperature elements for 1710, melting of SiO2, due to the surface tension of molten layer, melt together, SiO2 lost protection. Next, oxidation atmosphere in again when using, SiO2 re-generate layer.
It must be pointed out that MoSi2 heating elementS can’t be 400-700 degrees within the scope of use for a long time. Because of the low or components will be strong oxidation and become powder.
