Wollastonite is a mineral from the silicate group and was named in honor of Sir William Hyde Wollaston (1766–1828). It consists of the elements calcium (Ca), silicon (Si), and oxygen (O), with the chemical formula CaSiO 3. Theoretically, wollastonite's composition consists of 48.38% calcium oxide (CaO) and 51.78% silicon dioxide (SiO 2 ...

Wollastonite's greater readiness to melt at higher temperatures has a curious side effect: Glazes can tolerate higher SiO 2 (from the Wollastonite) and melt just as well or better. In glass and fiberglass making wollastonite melts more readily (lower energy costs) and microbubble generation is lower than limestone-sand mixes.
Wollastonite is widely used as a flux in the casting of steel and in the production of paints and coatings. In paints, wollastonite provides rein forcement, hardening, low oil absorp …
An alternative method for synthesising wollastonite with controlled properties is the two-step method, which starts with the preparation of precursors in an aqueous medium followed by calcination in the temperature range of 700–1100 °C [36].Synthesis can be carried out using different sets of reagents and additives, for …
Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Wollaston (1766–1828). It is composed of calcium (Ca) and silicon and …
Moreover, our findings indicate that, under the exposure conditions of the Finnish mine and mill in our study, wollastonite fibers are poorly retained in human lungs. This finding may also explain the absence of fibrosis in our material" (pp. 46-47) Hillerdal (2001) noted that in industrialized countries in the cities 2 to 4% of all males above ...
Baum (1972) noted that this material is similar to that from Willsboro, Essex County, New York, and that several tons of the New York material had been brought to the Franklin Mill for experimental purposes; thus, local collections may be tainted in part. Much Sterling Hill wollastonite has been found between the 340 and 1600 levels, near the ...
Wollastonite (CaSiO 3) is a vital mineral because of its utility in industry.It is a typical calc-silicate formed in skarn environments. Skarn is defined by its mineralogy, usually characterized by a calc-silicate assemblage of mainly garnet, pyroxene, and amphibole, besides wollastonite.
