Wollastonite is featured with good heat resistance, hard wearing and corrosion resistance, and strengthening and reinforcing functions. Being innocuous, flavorless, and non-radioactive, wollastonite is environmental type functional material that is extensively applied in the fields of plastics, rubber, paint, friction materials, building materials and metallurgy protection.
