Wollastonite can reduce the sintering temperature and shorten the sintering time, achieve a low-temperature sintering, and can save a lot of fuel, improve the mechanical properties of the products, reduce crazing, crack, breakage, enamel defects, such as warping and enamel defect problems. It also can improve embryo strength, reduce the product weight, increase luster glaze, reduce the glaze mud viscosity.then it can significantly reduce costs, improve the quality of ceramic products and yields. Because of good insulation, high impact strength and shape stability,it can be applied to electricity insulating ceramic industry, precision technology ceramics and ceramic industries.
