Applications of SiC and MoSi2 Heating Elements

Application guidance for silicon carbide and molybdenum disilicide heating elements in ceramics, glass, metallurgy, laboratory and industrial furnaces.

Typical Industries And Processes

  • Technical ceramics: sintering, firing, calcination and controlled heating in box, shuttle, roller and continuous kilns.
  • Magnetic materials and ferrites: pre-firing and sintering processes where furnace design and atmosphere are technically suitable.
  • Glass and related processing: selected melting, conditioning, forehearth, annealing and laboratory applications.
  • Powder metallurgy and advanced materials: sintering, calcination and heat treatment where electric resistance heating is appropriate.
  • Refractory materials: firing and thermal processing of bricks, castables, shapes and test samples.
  • Laboratory and research furnaces: high-temperature testing, material development and controlled-atmosphere work, subject to element-grade and furnace-design limits.

Choosing Between Sic And Mosi2

  • The correct choice cannot be made from furnace temperature alone. The assessment should include element temperature, atmosphere, contaminants, thermal cycling, furnace construction, chamber size, voltage, power-control method, surface loading and expected maintenance conditions.
  • SiC elements are widely used for industrial and laboratory resistance heating and are available in many straight, U-shaped, multi-leg and special configurations. MoSi2 elements are commonly considered for higher-temperature applications, but grade designation does not by itself guarantee the achievable furnace temperature.

Information Required For Application Review

  • Please provide the process material, target furnace temperature, atmosphere, furnace dimensions, existing element type, electrical data, installation direction, duty cycle, contamination sources, drawing and photographs.
