GM-L type silicon-molybdenum rod
Silicon-molybdenum rod resistive heating elements are high-temperature, oxidation-resistant resistive heating components made from molybdenum disilicide. When used in a high-temperature oxidizing atmosphere, a bright and dense quartz (SiO2) glass film forms on the surface, which protects the inner layer of the silicon-molybdenum rod from further oxidation. Therefore, silicon-molybdenum rod elements have unique high-temperature oxidation resistance.

Product Description
Silicon-molybdenum rods are resistive heating elements made of molybdenum disilicide, which are high-temperature resistant and oxidation-resistant. When used in a high-temperature oxidizing atmosphere, a bright and dense quartz (SiO2) glass film forms on the surface, protecting the inner layer of the silicon-molybdenum rod from further oxidation. Therefore, silicon-molybdenum rod elements have unique high-temperature oxidation resistance.
In an oxidizing atmosphere, with a maximum operating temperature of 1800℃, the resistance of silicon-molybdenum rod heating elements increases rapidly with temperature. When the temperature remains constant, the resistance value stabilizes. Under normal circumstances, the resistance of the element does not change with the duration of use, so new and old silicon-molybdenum rod heating elements can be used interchangeably.
Correctly selecting the surface load of the heating element based on the structure, working atmosphere, and temperature of the heating device is key to the service life of silicon-molybdenum rod heating elements.

Equal diameter silicon carbide rods are alternative products to coarse end silicon carbide rods, featuring advantages such as low end resistance, long service life, and energy saving. They are commonly used in industries such as rare earth phosphors, electronics, magnetic materials, powder metallurgy, and precision casting, serving as heating elements for push plate furnaces, mesh belt furnaces, trolley furnaces, and box furnaces.
U-shaped silicon molybdenum rod
U-shaped silicon molybdenum rod: The double-handled U-shaped design component is the most commonly used type. The heating end is welded to the cold end terminal part, while the cold end diameter is twice that of the heating end diameter. This specification is the most commonly used specification and is generally used for vertical suspension.
