steatite Mineral talc ceramic high-frequency insulation media loss electronic parts
Product name : Talc Porcelain
Specification : HY-HSC
Introduction of talc porcelain :
Talc porcelain is made of mineral talc ( 3MgO.4SiO2.H2O ) as the
main raw material, adding appropriate amount of clay and BaTiO3 and
other ingredients by mixing grinding, molding and high temperature
sintering. The main crystal phase of talc porcelain is the original
enstatite, that is, magnesium metasilicate ( chemical formula is
Mgsio3 ). It is a high-frequency structural ceramic with excellent
electrical properties, dielectric loss, and low price. It is mainly
used in high-frequency coil skeletons, electrical and radio
equipment, lead terminals, insulators, and various wiring board
tubes and switches. It has high insulation strength, no fatigue and
aging, and good electrical performance.
