Product Description

Silicon Molybdenum Rod Heating Elements | High-Temp for Muffle Furnace

High-Performance Silicon Molybdenum Rod (MoSi2) Heating Elements for Your Muffle Furnace

Upgrade your high-temperature processes with our premium Molybdenum Disilicide (MoSi2) heating elements. Engineered for excellence in oxidizing atmospheres, these rods deliver reliable performance up to 1800 °C (3272°F), making them the ideal heating solution for muffle furnaces and a wide range of industrial applications.

Key Features & Benefits

Extreme Temperature Resistance: Stable operation in oxidizing environments from 1300 °C to 1800°C.
Superior Oxidation Resistance: Automatically forms a protective SiO2 glass film at high temperatures, preventing further oxidation and extending service life.
Long Service Life & Stability: The resistivity remains stable over time, allowing for the mixing of old and new elements without performance loss.
Multiple Configurations Available: Choose from standard U-type, W-type, right-angle, circular types, or request custom shapes to fit your specific furnace layout.
Wide Application Range: Perfect for metallurgy, glass, ceramics, magnetic materials, refractory materials, crystal growth, and electronic device manufacturing.

Physical & Chemical Properties

Our MoSi2 heating elements boast exceptional material properties that guarantee durability and performance under thermal stress.

Property	Value	Significance
Volume Density	5.5 g/cm³	Ensures structural integrity at high temperatures.
Bending Strength	15-25 kg/cm²	Provides good mechanical strength in the brittle state.
Heating Elongation Rate	4%	Critical for proper installation and thermal expansion planning.
Porosity	7.4%	Low porosity contributes to better oxidation resistance.
Protective Mechanism	Forms self-healing SiO2 layer	The key to its unmatched oxidation resistance at high temperatures.

Proper Installation for Maximum Lifespan

Correct installation is crucial to prevent damage and ensure a long service life.

Handle with Care: MoSi2 elements are brittle at room temperature. Avoid mechanical impact or stress.
Vertical Suspension (Recommended): For U-type elements, hanging them vertically is the preferred method. This avoids putting direct mechanical stress on the hot zone.
Horizontal Support: If horizontal installation is necessary, use a high-temperature refractory support to cradle the element along its length.
Electrical Connections: Use appropriate clips and ensure the contact voltage is below 0.1V. Maintain a distance of > 50mm between the clip and the furnace brick to prevent overheating.

Applications in Industrial Furnaces

Our Silicon Molybdenum Rods are universally applied as the ideal heating element for:

High-Temperature Annealing Furnaces
Laboratory and Industrial Muffle Furnaces
Sintering Furnaces for ceramics and advanced materials
Heat Treatment Furnaces
Glass Melting and Ceramic Kilns
