Wollastonite for Ceramic (0-10mm)

Product Description

Wollastonite can reduce the sintering temperature and shorten the sintering time, achieve a low-temperature sintering, and can save a lot of fuel, at the same time improve the mechanical properties of the products, reduce crazing, crack, breakage, enamel defects, such as warping and problems. It can also improve green strength, reduce the product weight, increase luster glaze, reduce the glaze mud viscosity. As a result, 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.
