Calcium Carbonate Powder Ca (CO3)

Description:

Calcium carbonate is a chemical compound with the chemical formula CaCO3. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but high consumption can be hazardous.

PreRish Tri is producing premium CaCO3 powder by crushing, grinding, precipitation, and classifying high purity, white, calcite limestone.

Formula: CaCO3  

Calcium Carbonate (CaCo3) Mineralogy:

Calcium carbonate 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.

Calcium Carbonate Magnum Gloss Grades Available: Magnum Gloss® M, Magnum Gloss® SAT, Magnum Gloss® XF

Typical Applications:

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, thermo sets, thermoplastics, paints, coatings, adhesives, sealants, rubber, pharmaceutical, toothpaste, and food additive

Calcium carbonate 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.

Calcium carbonate 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.
