The Process of Making Silicon Carbide Heating Elements

Silicon carbide (SiC) heating elements are made from high-purity silicon carbide, a black, high hardness material that is highly resistant to thermal shock and chemical corrosion. The process of making silicon carbide heating elements has the following steps, including.

  1. Raw material preparation. High-purity silicon carbide powder is first prepared.
  2. Compacting. The powder is pressed to the desired shape using a high-pressure machine.
  3. Sintering. Sinter the blanks in a high-temperature furnace to produce a dense, uniform material.
  4. Shaping. The sintered material is then shaped by a special machine into the desired shape, usually in rods or rolls.
  5. Heat treatment. The shaped element is then heat treated to further improve its mechanical strength and electrical conductivity.

Make MoSi2 heating elements

MoSi2 heating elements are made from molybdenum disilicide (MoSi2), a refractory compound with a high melting and boiling point. The process of manufacturing MoSi2 heating elements involves several steps, including.

Raw material preparation. First, high-purity molybdenum and silicon are prepared.

  1. Mixing. Molybdenum and silicon are then mixed in the correct proportions to form MoSi2 powder.
  2. Compacting. The MoSi2 powder is then pressed into shape using a high pressure press.
  3. Sintering. The raw material is then sintered in a high-temperature furnace to produce a dense, homogeneous material
  4. Shaping. The sintered material is then shaped into the desired shape using a specialized machine.
