Wollastonite (silicate, chemical formula CaSiO 3) exists in an acicular and non-acicular form. Elements listed: Ca, O, Si - search for minerals with similar chemistry. The Chemical Identifier fields include common identification numbers, the NFPA diamond U.S. Department of Transportation hazard labels, and a general description of the chemical. It is composed of calcium (Ca) and silicon and oxygen (SiO2, silica) with the chemical formula CaSiO3. Natural wollastonite is an acicular (needle-like) calcium silicate mineral that occurs in triclinic and monoclinic varieties; these varieties are very difficult to distinguish from one another. Wollastonite is rarely found by itself, and ore zones in the major deposits contain 20-98% wollastonite. Mineral: Wollastonite . Wollastonite 13983-17-0 40-90% Wollastonite, a naturally occurring calcium silicate, is known to contain some quartz (silica), and feldspar. Wollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen. Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Wollaston (1766–1828). Crystallography of Wollastonite-1AHide Crystal System: Triclinic. The information in CAMEO Chemicals comes from a variety of data sources. Wollastonite was named after W.H. 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. Chemical Formula: CaSiO3 or … Wollastonite can be characterised by: Shape (non-acicular/ acicular) Medium Mohs h ardness of 5; Alkaline nature . Wollastonite is an A natural calcium silicate mineral found in metamorphic rock Wollastonite uses and applications include: Extender, filler, pigment for paints, plastics, rubber, friction, refractory, cements, wallboard, ceramics, construction, sealants, adhesives, welding rod coatings, silica gels, paper coatings; mineral wool; soil conditioner; flatting agent in powder coatings ... Molecular formula. Although much wollastonite is Wollastonite (Ca(SiO3)) ... CAS (Chemical Abstract Service) registry number. Wollastonite–A Versatile Industrial Mineral What is Wollastonite? The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Chemical Properties of Wollastonite-1AHide. Any of these ions may partially substitute for calcium if they are present. Wollastonite (calcium silicate, chemical formula CaSiO 3) exists in an acicular and non-acicular form. Natural wollastonite may contain trace or minor amounts of various metal ions such as aluminum, iron, magnesium, potassium and sodium. Chemical Name: Calcium metasilicate. Space Group: P 1. Wollaston, an English chemist and mineralogist. Class (H-M): 1 - Pinacoidal. Section III. It is usually white. Its molecular formula is CaSiO3 and its theoretical composition consists of 48.28% CaO and 51.72% SiO2. Wollastonite can be characterised by: Shape (non-acicular/ acicular) Medium Mohs hardness of 5; Alkaline nature. Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium.
