    Calcium carbonate

     

    Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous. 

    Biological sources

    Eggshells, snail shells and most seashells are predominantly calcium carbonate and can be used as industrial sources of that chemical.Oyster shells have enjoyed recent recognition as a source of dietary calcium, but are also a practical industrial source. Dark green vegetables such as broccoli and kale contain dietarily significant amounts of calcium carbonate, however, they are not practical as an industrial source.

     

    Geology

    Carbonate is found frequently in geologic settings and constitutes an enormous carbon reservoir. Calcium carbonate occurs as aragonite, calcite and dolomite as significant constituents of the calcium cycle. The carbonate minerals form the rock types: limestone, chalk, marble, travertine, tufa, and others.

     

    In warm, clear tropical waters corals are more abundant than towards the poles where the waters are cold. Calcium carbonate contributors, including plankton (such as coccoliths and planktic foraminifera), coralline algae, sponges, brachiopods, echinoderms, bryozoa and mollusks, are typically found in shallow water environments where sunlight and filterable food are more abundant. Cold-water carbonates do exist at higher latitudes but have a very slow growth rate. The calcification processes are changed by ocean acidification.

     

    Where the oceanic crust is subducted under a continental plate sediments will be carried down to warmer zones in the asthenosphere and lithosphere. Under these conditions calcium carbonate decomposes to produce carbon dioxide which, along with other gases, give rise to explosive volcanic eruptions.

     

     

    Rubber industry
    Calcium carbonate is one of the earliest and largest fillers used in the rubber industry. Calcium carbonate is filled in rubber in large quantities, which can increase the volume of the product, thereby saving expensive natural rubber and reducing costs. Calcium carbonate can be obtained by filling rubber. Pure rubber sulphide has higher tensile strength, tear strength, and a significant reinforcing effect in natural rubber and synthetic rubber, while adjusting the consistency.Plastic industry


    Calcium carbonate can play a skeleton role in plastic products, has a great effect on the dimensional stability of plastic products, can improve the hardness of the products, and can also improve the surface gloss and surface flatness of the products. The addition of calcium carbonate to general plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is above 90%, it can also replace the expensive white pigment to play a certain whitening effect.
