Wollastonite
Wollastonite(calcium metasilicate, or CaSiO3) it's a naturally occuring white mineral which acts as an acicular reinforcing filler.
1) Replace asbestos to be apply for friction material field
2) Replace glass fibre
3) Apply for plate and frame of filter press
3) Widely applied in ceramic, paint, as electrode coating, plastic, insulating material, paper and ect.
