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 limestone 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.Processing of superfine wollastonite,Processing of superfine wollastonite. Date:2019-02-17 16:31. Wollastonite is a new type of mineral raw material, natural needle-like white crystal, free of crystal water, low water absorption, no dehydration by heating, relatively late in appearance, widely used in ceramics with unique mineralogical and physicochemical properties.Wollastonite - an overview | ScienceDirect Topics,Wollastonite’s fiber-like shape provides similar properties as those of the glass fibers discussed below, and also like glass, its abrasiveness can damage processing equipment. However, unlike other mineral fiber, asbestos, its particles are nonhazardous [1-1, 3-4, 7-6, 7-13, 7-15] 1-1 3-4 7-6 7-13 7-15.
