How to distinguish the good or bad of kaolin?
Kaolin chemical composition analysis laboratory test kaolin composition is very complex, kaolin chemical composition contains a large number of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, and trace amounts of K2O, Na2O, CaO and MgO.
Kaolin is based ceramic preform molding, has good plasticity and binding, can effectively reduce the deformation and cracking of the embryo, with high fire resistance and burning degree, can enhance the mechanical strength, can improve the thermal stability and chemical stability and sintering properties, good suspension property and adsorption in ceramics in the process of color glaze. The product also has three oxidation, two aluminum content, high iron, manganese, titanium and other harmful impurities, low ore, ore and concentrate quality stability, etc., is a high quality kaolin.
