Wollastonite (silicate, chemical formula CaSiO 3) exists in an acicular and non-acicular form. Wollastonite is rarely found by itself, and ore zones in the major deposits contain 20-98% wollastonite. Physical Data for Material Physical State: Solid Odour and Appearance: Odourless; white and light green finely grained material Odour Threshold: Not … Basic properties Wollastonite can be characterised by: Shape (non-acicular/ acicular) Medium Mohs h ardness of 5; Alkaline nature . Wollastonite (calcium silicate, chemical formula CaSiO 3) exists in an acicular and non-acicular form. Mineral: Wollastonite . Wollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen. 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. Chemical Properties of Wollastonite-1AHide. Crystallography of Wollastonite-1AHide Crystal System: Triclinic. Wollaston, an English chemist and mineralogist. It is composed of calcium (Ca) and silicon and oxygen (SiO2, silica) with the chemical formula CaSiO3. Formula: CaSiO 3. Chemical Formula: CaSiO3 or … 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. Although much wollastonite is Space Group: P 1. Wollastonite–A Versatile Industrial Mineral What is Wollastonite? Associated minerals are most often calcite, garnet, and diopside. Section III. Any of these ions may partially substitute for calcium if they are present. Wollaston (1766–1828). 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. ... Molecular formula. Wollastonite was named after W.H. Its molecular formula is CaSiO3 and its theoretical composition consists of 48.28% CaO and 51.72% SiO2. Wollastonite is a chemically simple mineral named in honor of English mineralogist and chemist Sir W.H. Natural wollastonite may contain trace or minor amounts of various metal ions such as aluminum, iron, magnesium, potassium and sodium. Wollastonite 13983-17-0 40-90% Wollastonite, a naturally occurring calcium silicate, is known to contain some quartz (silica), and feldspar. The information in CAMEO Chemicals comes from a variety of data sources. Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. Chemical Name: Calcium metasilicate. 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. Class (H-M): 1 - Pinacoidal. 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 Basic properties Wollastonite (Ca(SiO3)) ...
