Abstract

The invention discloses micron-sized plate-like zirconium silicate powder and a preparation method thereof. The preparation method comprises the following steps of: uniformly mixing zirconium oxide, silicon dioxide, a molten salt and a forming agent to obtain a reactant; controlling the mol ratio of the zirconium oxide, the silicon dioxide and the forming agent to be 1: 1.05-1.10: 1-3: 0.005-0.04;placing the reactant in a closed container and keeping the temperature at 850-1150 DEG C to obtain a calcined product; and washing and drying the calcined product to obtain the micron-sized plate-like zirconium silicate powder. The preparation method is simple in process, less in environmental pollution and easy for industrial production. The prepared zirconium silicate powder has good crystallization, few defects, regular plate-like shape, micron-sized size and uniform distribution; when the micron-sized plate-like zirconium silicate powder is applied to ceramic glazed tiles, the wear resistance and skid resistance of the ceramic glazed tiles can be obviously improved, the opacifying effect is weak, and the ceramic glazed tiles have good application effect.

Description

technical field [0001] The invention relates to a zirconium silicate powder, in particular to a zirconium silicate powder in the form of a micron plate and a preparation method thereof. It belongs to the field of inorganic materials. Background technique [0002] Zirconium silicate (ZrSiO 4 ) has a high melting point, low thermal conductivity, small thermal expansion coefficient, high hardness, and good chemical stability. It can be used as an opacifying agent, wear-resistant material, and anti-skid material in the field of architectural ceramics. Adding zirconium silicate powder with higher hardness into the glaze, or directly separating zirconium silicate crystals from the glaze, can significantly increase the wear resistance and anti-skid performance of glazed tiles. However, if the preparation process is not well controlled, the zirconium silicate powder is in the nanometer or submicron scale, which will produce obvious opacification effect. Therefore, at present, the...
