    SA Series Superfine Wollastonite Powder

    Wollastonite is a typical metamorphic mineral, which has primarily occurred in contact
    belt between acid rock and limestone, and sometimes occurred in deep metamorphic
    Calc schist, volcanic product and in some alkaline rock. The chemical molecular
    formula of Wollastonite is CaSiO3, and structural formula is Ca3 [Si3O9], the theoretical
    chemical compositions: 48.25% CaO, 51.75% SiO2.
    Wollastonite is a thin plate-like crystal of triclinic crystal system whichbelongs to a chain
    silicate. Its aggregation is radial or fibrous. Its special crystal structure determines its
    properties, Wollastonite with the advantage of non-toxic, acid and alkali resistant, low
    hygroscopicity, low oil absorption, low conductivity, good insulation, high whiteness,
    thermal stability and dimensional stability good, excellent mechanical properties and
    electrical characteristics. Wollastonite is a natural green, low carbon emission and energy
    saving industrial mineral.
