Ceramic body material
Potash feldspar in the ceramic industry in the amount of about 40% of the total amount of potassium feldspar. Potash feldspar in the ceramic three components (china clay, quartz, feldspar) billet system, in addition to the supply of Al2O3 and SiO2, but also provide alkali metal oxide, both barren raw materials, but also flux raw materials. Potash feldspar can be used as raw material before sintering to reduce the shrinkage and deformation of the green body, improve the drying performance, shorten the drying time; in the firing can be used as a flux to reduce the firing temperature, to promote the melting of quartz and kaolin, And in the liquid phase to spread through each other to accelerate the formation of mullite, and the formation of feldspar vitreous filled with the mullite between the green body, so that the body is dense and reduce the gap, thereby enhancing its mechanical strength and Dielectric properties. In addition, the formation of feldspar glass can also improve the transparency of the green body and transparency, to give the body a higher mechanical strength and chemical stability.
Ceramic glaze is mainly composed of feldspar, quartz and clay raw materials, of which the most commonly used potassium feldspar amount can reach 10 ~ 35%, is the main component of the formation of glass phase, with a wide melting range and large high temperature viscosity , Can broaden the melting of the glaze melting temperature range, is conducive to porcelain and reduce the firing temperature, improve glaze layer gloss, transparency and smoothness, improve the glaze layer of chemical stability, improve product quality and quality level.
