China Steatite Ceramic Part&Insulation Ceramic Technical Ceramic

1. Product description
The main material of Steatite is mineral talc (3MgO.4SiO2.H2O), adding an appropriate amount of clay and other ingredients, finally made by mixing ground, shaping and high temperature sintering process.
Steatite has good dielectric properties and mechanical strength with low price, and low dielectric constant, low dielectric loss tangent value, high dielectric strength, high volume resistivity, in addition, it has a high bending strength and relatively static good chemical stability --High corrosion resistance, Acid and alkali resistance.
Because the dielectric constant of steatite reduced with the increasing frequency, and at high frequencies with increasing temperature, the change is very small.so the steatite will show the advantages for Ceramic components of high-frequency devices,
Steatite is a high frequency and ultrahigh frequency porcelain insulation material, widely used in electronic components, electronic device and electric product, or High power / High temperature application and ect.
