Wollastonite

Wollastonite is a naturally occurring calcium silicate mineral that is white in color. It is usually formed through the metamorphism of limestone and is commonly found in the form of needle-like crystals. Wollastonite has a low thermal expansion coefficient and high brightness, making it an ideal filler material for a variety of applications.
