Product Description

Wollastonite is a typical metamorphic mineral, mainly produced in the contact zone between acidic rock and limestone, and also appears in metamorphic calcium schist, volcanic products and some alkaline rocks.

 

The chemical molecular formula of wollastonite is Casio, the structural formula is Ca(SiO2], and the theoretical chemical composition is: 48.25% CAQ, 51.75% Sio. Wollastonite is a thin plate crystal of the triclinic system, which is a radial or fibrous aggregated chain silicate. Its special crystal structure determines its properties such as non-toxic, acid and acid resistance, low moisture and oil absorption, good insulation, high whiteness, good thermal and dimensional stability, excellent mechanical and electrical properties.

Wollastonite is also known as a natural green, low-carbon emission, energy-saving industrial mineral raw material.
