Product Introduction As a typical metamorphic mineral, Wollastonite has primarily occurred in the contact belt between acid rock and limestone, alsoappeared in katametamorphic calc schist, volcanic product and certain alkaline rock. The chemical molecular formula of Wollastoniteis CaSiO3, the structural formula is Ca3 [Si3O9], the theoretical chemical compositions: 48.25% CaO, 51.75% SiO2. Wollastonite is thin plate-like crystal of triclinic system which belongs to a chain silicate with radial or fibrous aggregation. Its specialcrystal structure determines the properties of non-toxic, acid & alkali resistant, low hygroscopicity & oil absorption, fine insulation,high whiteness, great thermal & dimensional stability,excellent mechanical & electrical performance. Wollastonite is further known as industrial mineral raw material with natural green, low carbon emission and energy saving.
