It consists of soapstone (Mg(Si4O10)(OH)2), which is also the main component, a natural magnesium silicate and additions of clay such as feldspar or barium carbonate. Steatite, produced from quality soapstone, has been widely used for insulation in the electrical and electronic industry. It is a low-cost material with high electrical resistance at high temperatures, good mechanical strength and a very low dielectric loss factor. Such characteristics make it ideal for high frequency, low loss and high voltage isolation.
Production methods:
Common production methods are dry pressing, extrusion, casting and moisture pressing
Characteristic features of steatite:
It is a lower cost material than alumina, but has excellent resistance properties (which can be maintained at high temperatures) and moderate mechanical strength.
