Wollastonite powder is a finely ground form of the mineral wollastonite. It is created by crushing, grinding, and processing natural wollastonite mineral deposits into a powder with specific particle sizes. This powdered form of wollastonite retains the mineral’s chemical composition but is much finer in texture, which makes it suitable for a wide range of industrial and commercial applications.
