  • Limestone Formula:

    CaCO3

  • Limestone Description:

a) Produced by crushing, grinding, precipitation, and classifying high purity, white, calcite limestone.

b) Among the important varieties of limestone are marl, chalk, oolite, travertine, dolomite, and marble.

  • Limestone Mineralogy:

    Limestone ores can be found in two of the three major types of rocks: sedimentary and metamorphic. Sedimentary rocks, as the name suggests, form from sediment or from transported fragments deposited in water. Limestone, for example, is formed from inorganic remains, such as shells and skeletons. Metamorphic rocks—such as marble, slate, quartzite—form when a rock mass is subjected to great heat and pressure. The principal element in the calcium carbonate ore is calcium (Ca). The ore may contain other elements—Magnesium (Mg), Iron (Fe) and Manganese (Mn)— that affect whiteness, hardness and specific gravity.

  • Limestone Typical Applications:

a) Plastics, rubber, coatings, inks, adhesives, and soil conditioner, building products, plastic filler, ceramic flux, asphalt filler, chemical processing, glass ingredient, water treatment, pesticide granules, dusting agent, welding rods coating, thermosets, thermoplastics, paints, coatings, adhesives, sealants, rubber, pharmaceutical, toothpaste, and food additive

b) Limestone has a wealth of uses: as a flux in steel production and in processing of non-ferrous metals; in bricks, mortar and concrete for construction; as a raw material in glass; in the construction of roads and dams; in the manufacture of paper, paints and dyes, carpeting and other floor coverings; and in the treatment of water, industrial waste, gases and household refuse. It is also used to reduce soil acidity in agriculture, to absorb water and add calcium in food products, and in sugar
extraction.

c) Limestone is a versatile additive for use in a wide range of plastic and elastomeric applications. Its regular and controlled crystalline shape and ultrafine particle size together with the hydrophobic surface coating, combine to the benefit of both polymer processing and subsequent physical properties.
