Applicate

ceramic industry：calcined kaolin plays a role of filling, thickening and whitening in ceramic glazes, which can improve the viscosity and fluidity of glazes, making them easier to apply and process. Meanwhile, the aluminum, silicon and other elements contained in calcined kaolin react with other glaze raw materials, generating special color and texture effects, enhancing the decorative effect of glazes.
