Wollastonite: The mineral Wollastonite information and ...

Wollastonite occurs in three different forms, depending on its crystallization mon Wollastonite is known as Wollastonite 1A, indicating that it is one form of Wollastonite that crystallizes in the triclinic system. The "1A" distinguishes it from two rarer forms of Wollastonite, which are scientifically different minerals since they crystallize differently: Wollastonite 2M and Wollastonite 7A.

Wollastonite - Wikipedia

Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure lizenithne or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks.

Crystal class: Pinacoidal (1), (same H-M symbol)Crystal habit: Rare as tabular crystals—commonly massive in lamellar, radiating, compact and fibrous aggregates.Crystal system: Triclinic, Monoclinic polytype existsMohs scale hardness: 4.5 to 5.0

    Wollastonite allows formulators to improve the cohesive strength of their coatings to obtain better corrosion and barrier properties, extend in-can stability and improve thermal stability at high temperatures. It has a low binder demand, low viscosity build and can easily be incorporated into both waterborne and solvent borne systems.
