Molybdenum Disilicide High Temperature Electric Heating Element, Silicon Molybdenum Rod High Temperature Element
Description of MoSi2 Heating Element:
Molybdenum disilicide (MoSi2) is a silicon compound of molybdenum. Because the radii of the two atoms are not much different and the electronegativity is relatively close, it has properties similar to that of metals and ceramics. The melting point is as high as 2030 ℃, and it is conductive. Under high temperature, a silicon dioxide passivation layer can be formed on the surface to prevent further oxidation. Its appearance is gray metal color, originating from its four sides α- A-type crystal structure, hexagonal but unstable β- Modified crystal structure. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid.

2.Chemical Properties of Physical Properties of MoSi2 Heating Element
Oxygen-resistance under high temperature: in oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of element owing to the high temperature combustion, which prevent Mosi2 from oxidizing more. When the element temperature is higher than 1700 °C, the film becomes melting. It’s not suitable for long time use in the temperature range of 400-700°C, otherwise, the element will be powdering for the strong oxidation under low temperature.
