Wollastonite belongs to a kind of chain like silicate and a fibrous and needle like shape. As the crystal structure of its special crystal determines its properties of non-toxic, acid &akai resistant, low hygroscopicity &oil absorption, fine insulation, high whiteness, great thermal & dimensional stability, xcellent mechanical &electrical performance. Wollastonite is widely used in ceramics, chemical industry, metallurgy, paper making, plastics, coatings and other fields.
