Description and Uses
“Wollastonite” occurs as a calcium inosilicate
mineral that may contain small amounts of Fe, Mg and
Mn substituting for calcium.
The manufactured salt is
usually white. It forms within the earth when impure
limestone is subjected to high temperature and pressure,
sometimes in the presence of silica-bearing fluids as in
metamorphic rocks. It is named after the English
chemist and mineralogist William Wollaston (1766–
1828).
Wollastonite crystallizes as a triclinic crystal with
the space group, 1, and the lattice constants: a = 7.94? ,
b = 7.32 ? , c = 7.07 ? ; α= 90.03°, β = 95.37°, γ = 103.43°
and six formula units per cell.
