Ceramic Friction CAS 13983-17-0 Grey White Wollastonite Powder
Ceramic Friction CAS 13983-17-0 Grey White Wollastonite Powder
As a typical metamorphic mineral, Wollastonite has primarily occurred in the contact belt between acid rock and limestone, also appeared in katametamorphic calc schist, volcanic product and certain alkaline rock.
The chemical molecular formula of Wollastonite is Casio the structural formula is Ca (SiO2], the theoretical chemical compositions:48.25%CAQ, 51.75% Sio Wollastonite is thin plate-like crystal of triclinic system which belongs to a chain silicate with radial or fibrous aggregation. Its special crystal structure determines the properties of non-toxic, acid &akai resistant, low hygroscopicity &oil absorption, fine insulation, high whiteness, great thermal & dimensional stability, xcellent mechanical &electrical performance.
Wollastonite is further known as industrial mineral raw material with natural green, low carbon emission and energy saving.
