Wollastonite belongs to a kind of chain metasilicate, and it is also a fibrous, needle-like silicate.

Because of its special crystal shape and crystal structure determine its properties, wollastonite has good insulation, and at the same time has high whiteness, good dielectric properties and high heat resistance and weather resistance. Because wollastonite is widely used in ceramics, chemical industry, metallurgy, papermaking, plastics, coatings and other fields.
