Ceramic parts | Electrical insulated ceramic | NBVIC
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramic is generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
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, which is recommended as an insulation material in electrical engineering.| Items | Alumina | Zirconia | Steatite | Mullite | Cordierite | |||
