Wollastonite is a kind of chain metasilicate, but also a kind of fiber, needle. Due to its special crystal shape and crystal structure, wollastonite has good insulation, high whiteness, good dielectric properties and high heat and weather resistance. Wollastonite is widely used in ceramics, chemical industry, metallurgy, paper making, plastics, coatings and other fields.
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.
