SW series - Wollastonite ultrafine needle shaped powder

Wollastonite is a typical metamorphic mineral that mainly occurs in the contact zone between acidic rocks and limestone. It is also found in deeply metamorphosed calcareous crystalline schists, volcanic eruptions, and certain alkaline rocks. Its chemical formula is CaSiO3, structure is Ca3 [Si3O9], and theoretical chemical composition is CaO 48.25% SiO2 51.75%.Wollastonite belongs to a type of chain like metasilicate, which is a triclinic system with fine plate-like crystals and aggregates in radial or fibrous form. Due to its special crystal morphology and crystal structure, its properties are determined. It has non-toxic, acid and alkali resistant, low moisture absorption, low oil absorption, low conductivity, good insulation, high whiteness, good thermal stability and dimensional stability, excellent mechanical and electrical properties, and other characteristics. It is natural green Low carbon and energy-saving industrial mineral raw materials.
