“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.
Chemische Eigenschaften
White to brown, red, gray, yellow solid; vitreous to pearly luster. Mohs hardness 4.5–5.
Physikalische Eigenschaften
Wollastonite occurs as bladed crystal masses, single crystals can show an acicular particle shape and usually it exhibits a white color, but sometimes cream, gray or very pale green. The melting point of wollastonite is about 1540°C.
Wollastonite is used primarily in ceramics, friction products (brakes and clutches), metalmaking, paint filler, and plastics.
Ceramics; paint extender; welding rod coatings; rubber filler; silica gels; paper coating; filler in plastics, cements, and wallboard; mineral wool; soil conditioner.
A natural calcium silicate found in metamorphic rocks.
Allgemeine Beschreibung
White or slightly cream-colored powder. pH (aqueous slurry) 8.0 to 10.0.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions. These materials may be nontoxic.
Questionable carcinogen
Flash point data for CALCIUM SILICATE are not available; however, CALCIUM SILICATE is probably nonflammable.
