Molybdenum Disilicide Heating Element - Diameter 3/6mm To 12/24mm, Length 150mm To 700mm | High-temperature Resistance, Anti-oxidation, Custom Shapes Available

Mosi2 heating element is a kind of resistance heating element made primarily of high-purity Molybdenum Disilicide. In an oxidizing atmosphere, a dense quartz protective film forms on the surface of the Mosi2 element due to high-temperature combustion, preventing continuous oxidation. In oxidizing atmospheres, its maximum temperature can reach 1800A C, with an applicable temperature range of 500-1700A C. It can be categorized into shapes such as "pole," "U," and "W," and special shapes like right angles and bends can be produced upon customer request.

Application:
Silicon molybdenum rod electric heating elements are widely used in metallurgy, steelmaking research and production, glassmaking, ceramics, refractory materials, crystal and semiconductor manufacturing, and other fields. They are especially valued in high-performance ceramics, precision optics, and advanced alloy steel production, including sintering and heat treatment processes for ceramics, magnets, glass, metallurgy, and refractories.

Advantages:
Mosi2 heating elements quickly form a thin, adherent anti-oxidizing quartz glass (SiO2) layer under high-temperature oxidizing conditions. If this protective layer is damaged, the element can regenerate a new one, providing excellent anti-oxidation properties and prolonged operational lifespan compared to traditional heating elements. The resistivity of Mosi2 remains stable over time, allowing for easy replacement without affecting existing elements, thereby reducing furnace maintenance costs and downtime, and enhancing operational efficiency.

Installation of Mosi2 Heating Element:

Vertically Hanging:
MoSi2 elements are very brittle at normal temperatures but become plastic at high temperatures. To prevent mechanical stress directly on the heat-generating end, U-shaped elements should be vertically hung from the furnace top using support clamping chucks.

Support Clamp:
Support clamps are used for 9/18 and 6/12 elements respectively to bear the weight and position the element vertically. Careful installation is necessary to avoid local overheating, ensuring the tapered end of the lower element is inside the furnace chamber.
