Wollastonite - Imerys
Wollastonite is a naturally occurring mineral that is a chemical combination of calcium, silicon and oxygen. Wollastonite’s unique chemistry and needle-shaped physical structure make it one of the world’s most versatile and effective value-added performance materials.
Wollastonite – Mineral Properties, Photos and Occurrence
2021年7月19日 · Wollastonite is a mineral most closely associated with metamorphosed carbonate rocks or silica-infused hydrothermal modifications of calcareous sediments. Typical wollastonite occurrence is in marbles with higher silica content. Other typical wollastonite bearing rocks are Ca-rich skarns and their subtype, sometimes labeled as erlan.
Wollastonite Statistics and Information | U.S. Geological Survey - USGS.gov
Wollastonite, a calcium metasilicate (CaSiO 3), has a theoretical composition of 48.3% calcium oxide and 51.7% silicon dioxide but may contain trace to minor amounts of aluminum, iron, magnesium, manganese, potassium, and sodium. It occurs as prismatic crystals that cleave into massive-to-acicular fragments.
The Mineral wollastonite - The Mineral and Gemstone Kingdom
Wollastonite is an industrially important mineral. It is a necessary ingredient in heat-resistant refractory ceramics and is used as a filler in paint. It is also used in the manufacture of paper and plastics. Due to its fluorescece, Wollastonite is a popular mineral among collectors who specialize in fluorescent minerals.
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 oxygen (SiO2, silica) with the chemical formula CaSiO3.
