Wollastonite --MIROFOSS--

Wollastonite is a calcium inosilicate mineral which is usually white. It is named after the English chemist and mineralogist William Hyde Wollaston (1766–1828). Some of the properties that make wollastonite so useful are its high brightness and whiteness, low moisture and oil absorption, and low volatile content. The major countries which produce wollastonite are China, India, United States, Mexico, and Finland.

Wollastonite – Sibelco

Mechanical reinforcement: due to its acicular structure, wollastonite will mechanically reinforce the binder matrix. Abrasion resistance: due to its hardness of 5 on Mohs scale, wollastonite will increase the coating’s resistance to wear. Rheology control: due to its acicular shape, wollastonite has an impact on the rheology profile. When applying shear, the acicular particles will align and provide a low viscosity.

Wollastonite is a naturally occurring, calcium metasilicate (CaSiO 3) mineral with a needle-like particle shape. Wollastonite is formed when impure limestone or dolostone undergo high temperature and pressure changes sometimes in the presence of silica-bearing fluids as in skarns or contact metamorphic rocks. It is usually white and can withstand temperatures over 1500°C.
