Wollastonite ---A white or grey mineral consisting of calcium silicate in triclinic crystal: Occurs in metamorsed
limestones, Formula: CaSiO3
Naturally occurring, calcium metasilicate (CaSiO3), white, non-metallic mineral with an acicular particle shape.Â
Wollastonite's unique chemistry and acicular (needle-shaped) sical structure make it one of the world's most versatile and
effective value-added performance materials.Â
Due to the mineral's acicular struture, products have improved sical properties and durability.Â
It's high melting point gives exent thermal stability in coatings, ceramics and other applications.Â
The high and low solubility of wollastonite aid paint stability.Â
Wollastonite is a non-hazardous mineral that has been seientifically shown to have low bio-persisitence.Â
