SPK MoSi₂ heating element

Silicon molybdenum rods soften slightly at high temperatures (above 1500 degrees) and become hard and brittle at low temperatures;

Silicon molybdenum rod resistive electric heating element is a type of resistance heating element made of molybdenum disilicide as the basis, which is resistant to high temperature and oxidation, and has unique high temperature and oxidation resistance.

Under an oxidizing atmosphere, the higher operating temperature is 1800 ℃ The resistance of silicon molybdenum rod electric heating elements increases rapidly with temperature, and the resistance value remains stable when the temperature remains constant. Under normal circumstances, the resistance of the component does not change with the length of use, so new and old silicon molybdenum rod electric heating elements can be mixed for use. (Temperature coefficient of resistance)

So the temperature for using irregular silicon molybdenum rods is generally not high, around 1550 degrees. High temperature can easily cause deformation.
