What is it?
Steatite is a crystalline form of magnesium silicate. It is a low-loss, low-cost insulation material with relatively good electrical resistance, which can work safely at high temperatures.
Applications
Ceramic steatite is an excellent material for electrical engineering, as it is easy to mould and sinter in a wide variety of shapes, such as washers, bushings, resistors, spacers and beads. Industrial applications of steatite include high-frequency insulation products, resistor cores and casings and insulators for household appliances and hydraulics.
