Wollastonite
Introduction:
Wollastonite belongs to a chain of metasilicates, is a fibrous, needle-like. Because of its special crystal morphology crystal structure determines its properties, wollastonite has good insulation, and has 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.

Applications:
Adding proper amount of wollastonite powder into ceramic raw material can greatly reduce the firing temperature, shorten the firing time, and realize low temperature rapid one-time firing. A large amount of fuel saving, significantly reduce product costs; At the same time, it can improve the mechanical properties of the products, reduce the cracks and warps of the products, increase the luster of the glaze, improve the strength of the embryo body, and improve the qualified rate of the products.
