  • Beschreibung Calcite is one of the most common minerals on the face of the earth, comprising about 4% by weight of the earth’s crust and is formed in many different geological environments. Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic, fossiliferous and massive limestones in sedimentary environments and even serves as the internal cement for many sandstones and shales.Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins. Not necessarily a variety of calcite, cave formations are certainly a unique aspect of calcite’s story.
  • Chemische Eigenschaften Ground limestone consists essentially of calcium carbonate. It is obtained by crushing, grinding, and classifying naturally occurring limestone benefited by flotation and/or air classification. It is pro duced as a fine, white to off-white, microcrystalline powder. It is odorless and tasteless and is stable in air. It is practically insoluble in water and in alcohol. The presence of any ammonium salt or carbon dioxide increases its solubility in water, but the presence of any alkali hydroxide reduces the solubility.
  • Chemische Eigenschaften Calcium carbonate is a white, odorless powder, or crystalline solid.
  • Verwenden Calcite is the primary mineral component in cave formations. Stalactites and stalagmites, cave veils, cave pearls, “soda straws” and the many other different cave formations that millions of visitors to underground caverns enjoy are made of calcite.
  • Verwenden Source of lime; neutralizing agent, filler, and extender in rubber, plastics, paints; opacifying agent in paper; fortification of bread; putty; tooth pow- ders; antacid; whitewash; Portland cement; sulfur dioxide removal from stack gases; metallurgical flux; analytical chemistry; carbon dioxide gener- ation (laboratory).
  • synthetische The calcite present is derived mostly from the remains of organisms such as clams, brachiopods, bryozoa, crinoids and corals. These animals live on the bottom of the sea and when they die their shells accumulate into piles of shelly debris. This debris ca
  • Definition Aragonite: An anhydrous mineral form of calcium carbonate, CaCO3, which occurs associated with limestone and in some metamorphic rocks. It is also the main ingredient of pearls. It is not as stable as calcite, into which it may change over time.
    Calcite:A mineral form of calcium carbonate occurring in limestone, chalk, and marble.
    Charlk: A natural form of calcium carbonate (CaCO3) formed originally by marine organisms. (Blackboard chalk is calcium sulfate, CaSO4.).
  • Allgemeine Beschreibung Odorless, white to tan powder.
  • Reaktivität anzeigen CALCIUM CARBONATE has generally low chemical reactivity. Is non-combustible. Decomposes at high temperature (825°C) to give gaseous carbon dioxide and calcium oxide (quicklime). Incompatible with acids, alum, ammonium salts, fluorine, magnesium. Reacts with acids and acidic salts to generate gaseous carbon dioxide with effervescence (bubbling). The reaction is rapid and exothermic with concentrated solutions of acids. The efferversence can create extensive foaming. Ignites on contact with fluorine.
  • Hazard A nuisance particulate dust.
  • Landwirtschaftliche Anwendung Limestone or dolomite, used in agriculture for liming the soil, is ground to a fineness to ensure that 50% of the particles pass through a 1.70mm Indian Standards (IS) sieve, and 50% is retained on a 150micron IS sieve.
  • Sicherheitsprofil A nuisance dust. An eye and skin irritant. Igmtes on contact with F2. Incompatible with acids, ammonium salts, (Mg + H2). Calcium carbonate is a common air contaminant. See also CALCIUM COMPOUNDS.
  • mögliche Exposition Calcium carbonate is used as a source of lime; neutralizing agent; manufacturing or rubber, plastics, paint and coatings; sealants, paper, dentifrices, ceramics, putty, polishes and cleaners, insecticides, inks and cosmetics; whitewash; Portland cement; antacids; analytical chemistry, and others
  • Inkompatibilitäten Calcium carbonate decomposes in high temperature forming carbon dioxide and corrosive materials
  • Waste disposal Landfills. It is the responsibility of chemical waste generators to determine if a discarded chemical is classified as a hazardous waste. See 40 CFR Parts 261.3 for United States Environmental Protection Agency guidelines for the classification determination. In addition, in order to ensure complete and accurate classification, waste generators must consult state and local hazardous waste regulations.
