Introduction
Wollastonite is a kind of natural minerals, its formula is CaSiO3 (Calcium-metasilicate). Based on its properties of high whiteness, natural brilliant acicular particle shape, besides of there properties, our wollastonite are processed with advanced technics and equipments, with high aspect ratio, good reinforcement and sealing property, more and more, it replaces asbestos, fiber talc, glass fiber, used in high polymer engineering plastics, special plastics, friction materials, etc sides. Also the wollastonite are widely used for Ceramic-body, Metallurgy, Painting, Welding and Glaze etc application.

Features 
-- As calcic metasilcate mineral, is a new kind of industrial raw mineral materials. 
-- White powder nd relative density is 2.8,melting point is 1554°C 
-- Good insulation performance, endure acid, resist abrade, bear high temperature.
