Ceramic grade wollastonite powder
Wollastonite can reduce the sintering temperature and shorten the firing time, achieve low-temperature and shorten the firing time, save a lot of fuel, improve the mechanical properties of the products, reduce crazing, cracking, breakage, wraping, enamel defects and other problems. It can also improve embryo strength, reduce the product weight, increase glaze luster, reduce the glaze mud viscosity, all of which reduce costs, and improve the quality and yields of ceramic products. With it’s excellent insulation properties, high impact strength and shape stability, it can be applied to the electrical insulating ceramic industry, precision technology ceramics industry and the craft ceramic industries.
