Steatite Ceramic
Steatite is an inorganic material based on natural raw materials consisting predominantly of magnesium silicate. It is marked by a high heat resistance, resistance to leakage current and dielectric strength. It is recommended as an insulation material in electrical engineering.
Structural ceramics have the characteristics of wear resistance,superior strength, hardness, insulation, heat conduction, high temperature resistance, corrosion resistance, high temperature refractory, etc.
