Product Description

As a typical metamorphic mineral, wollastonite mainly occurs in the contact zone between acidic rock and limestone, and also occurs in metamorphic rock calcareous 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: 48.25% CAQ, 51.75% Sio. Wollastonite is a thin plate-shaped triclinic crystal, which belongs to chain silicate and is radial or fibrous. Aggregation. Its special crystal structure determines that it has the characteristics of non-toxic, acid and alkali resistance, low moisture absorption and oil absorption, good insulation, high whiteness, good thermal stability, good dimensional stability, and excellent mechanical and electrical properties.

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