Cordierite Ceramic

The main raw materials of cordierite ceramics are talc, clay, alumina, feldspar and the like. Made using a general ceramic process. The sintering range is narrow, and the sintering temperature differs only a few degrees from the decomposition temperature of cordierite, making it difficult to obtain a dense body. As an additive, chlorite, magnesium carbonate, cesium carbonate, zirconium silicate, zirconium dioxide, boron trioxide, spodumene, etc. are generally used as additives to lower the sintering temperature, expand the firing temperature range, and improve the dielectric. performance. It can be used as a coil former, an arc-resistant electrical insulating material, a base material of a composite material, a material of a burner nozzle of an electric heating insulating device, and the like.
