wollastonite

[′wu̇l·ə·stə‚nīt] (mineralogy) CaSiO₃ A white to gray inosilicate mineral (a pyroxenoid) that crystallizes in the triclinic system in tabular crystals and has a pearly or silky luster on the cleavages; hardness is 5-5.5 on Mohs scale, and specific gravity is 2.85. Also known as tabular spar.

Wollastonite

(named after the English scientist W. H. Wollaston, 1766-1828), also tabular spar, a silicate mineral with a chain structure and a circular radical. Its chemical formula is Ca₃(Si₃O₉), and it sometimes contains traces of iron. Wollastonite crystallizes in a triclinic system, forming flat tabular crystals as well as radiated and conchoidal aggregates; its color is white and sometimes pink. It has a hardness of 5-5.5 on the mineralogical scale and a density of 2,780-2,920 kg/m³. Wollastonite is formed by contact and plutonic regional metamorphism of limestones.
