Steatite Ceramic Introduction

Steatite Ceramic(C221,commonly known as high-frequency ceramic) is a kind of ceraimc material used natural mineral talc (hydrous magnesium silicate, chemical formula 3MgO · 4SiO2 · H2O) as the main raw material, with magnesium metasilicate as the main crystalline phase.

Steatite Ceramic is widely used in high voltage insulation and electrothermal industry due to its excellent dielectric properties, low cost, low dielectric constant, dielectric loss tangent, high dielectric strength and volume resistivity. And chemical stability, with good acid, alkali, corrosion resistance.

Shengda Ceramics Steatite Ceramic include: Injection molding machine heating coil with porcelain tile, ceramic terminal block, ceramic lamp holder lamp base,  quartz tube ceramic insulator and other electrical and electronic insulation and insulation fields need to use ceramic pieces.
