Xinyu South Wollastonite XYNFW-A

Xinyu South Wollastonite XYNFW-A 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. 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.
