Main characteristics of Wollastonite
The chemical formula of wollastonite is CaSiO3, the structural formula is Ca3[Si3O9], and the theoretical chemical components are CaO 48.25% and SiO2 51.75%. In nature, pure wollastonite is rare, and in its formation, Ca is sometimes replaced by Fe, Mn, Ti, Sr plasma, and is isomorphous, with a small amount of Al and trace amounts of K and Na.
Wollastonite is a chain metasilicate, and is a kind of fiber like needle. Because of its special crystal morphology, crystalline structure determines its properties. Wollastonite has good insulation, high whiteness, good dielectric properties and high heat resistance and weather resistance. Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on.
