    Calcite: The mineral Calcite spar information and pictures

    Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in ...

    An example of such a special property is the effervescent reaction of calcite to a weak solution of hydrochloric acid (5% HCl). Calcite fizzes or effervesces as the HCl solution dissolves it and creates CO 2 gas. Calcite is easy to identify even without testing the reaction to .

    Calcite

    Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even ...

    Physical properties. Calcite is colourless or white when pure but may be of almost any colour—reddish, pink, yellow, greenish, bluish, lavender, black, or brown—owing to the presence of diverse impurities. It may be transparent, translucent, or lustre ranges from vitreous to dull; many crystals, especially the colourless ones, are vitreous, whereas granular masses, especially ...

    Green Calcite – Meaning, Benefits and Properties

    A special feature of calcite is its double refraction of light, which gave its name to the variety, the double spar. Due to this special property, pure crystals are also used in the optical industry. Calcite is less suitable as a gemstone because of its low hardness, but is .

    Double Refraction or Birefringence of Calcite

    Double Refraction. Calcite acts as though it were made of two materials. Such birefringent materials have different internal indices of refraction. They depend upon the orientation between the crystal lattice and the light striking it. The more the indices vary, the greater the splitting. Calcite has one of the largest divergences known.
