Silica fume for matte brick

Silica fume for matte brick: This microsilica is usually used in the manufacture of matt tiles to increase the glossiness of the glaze and other properties of the tiles. Because silica fume for ceramics has a low coefficient of expansion and low water solubility, in firing silica fume for ceramics can reduce firing shrinkage, significantly change the product of flexure and cracks, and easy to form. The use of silica fume for ceramics can optimise the quality of ceramic glaze and improve the glaze quality. In the daily ceramic glaze in the appropriate amount of wollastonite, can replace part of the quartz and limestone raw materials, can completely avoid the carbon dioxide gas discharged due to the decomposition of limestone, caused by the glaze pinhole and glaze bubble defects. In the firing silica fume for ceramics can reduce the high temperature viscosity of the glaze, optimise the gloss and smoothness of the porcelain glaze. The use of silica fume for ceramics needle-like…
