2.What is wollastonite and application :     
Wollastonite is a naturally occurring mineral with many unique characteristics. Through advanced processing, it has become one of the most versatile functional fillers in the marketplace. Wollastonite increases the performance of many products including plastics, paints and coatings, construction materials, friction, ceramic and metallurgical applications to name a few.

Wollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen. Its molecular formula is CaSiO3 and its theoretical composition consists of 48% CaO and 51% SiO2. Natural wollastonite may contain trace or minor amounts of various metal ions such as aluminum, iron, magnesium, potassium and sodium. Wollastonite is rarely found by itself and generally contains other minerals like calcite, garnet and diopside that are removed during processing.

Optimum performance is created by properly matching the correct coupling agent at the right concentration level to the polymer system. Overall, the benefits of a surface modified wollastonite are improved physical properties, improved processing along with improved dispersion of the resin.
2nd.Application:Wollastonite can be widely used in metallurgy industry,construction industry,automobile industry,paper industry,plastics & rubber industry,ceramic industry etc..
