Kanthal Super Heating Elements

KANTHAL SUPER is a dense cermet material consisting of MoSi2 and an oxide component, mainly a glass phase. KANTHAL SUPER has the ability to withstand oxidation at high temperatures. This is due to the formation of a thin and adhesive protective layer of quartz glass on the surface. When MoSi2 reacts with oxygen in the atmosphere, the layer of quartz glass is formed and under this a thin layer of molybdenum silicide with a lower silicon content Mo5Si3.

When KANTHAL SUPER elements are operated at temperatures around 1200 °C (2190 °F) the material becomes ductile, whilst at lower temperatures the material is more brittle. The silica layer possesses the capacity to clean itself from adhering impurities. If the impurities react with silica, the melting point will be lowered. The contaminated layer then flows down the element and drops off. A new silica layer is, however, spontaneously rebuilt.

The new properties also include a better hot strength and form stability. Kanthal Super therefore, can be used in horizontal applications with less deformation, although it still needs to be supported.
