Calcium carbonate, commonly known as travertine, limestone, stone, marble, calcite, is a compound of the formula is CaCO3, alkaline, substantially insoluble in water, soluble in acid.
It is a common substance on Earth, exists in the aragonite, calcite, chalk, limestone, marble, travertine and other rocks. Is also a major component of animal bones or shell. Calcium has a variety of physiological effects, such as participation in the formation of bone tissue and build bone fracture, involved in muscle contraction, nerve transmission, glandular secretion, visual physiology and blood clotting mechanism. Calcium deficiency, children susceptible to rickets, bone growth resulting in poor teenagers, the elderly prone to osteoporosis, bone hyperplasia. Can also be used hypocalcemia hyperphosphatemia in renal failure, mild metabolic acidosis, hyperacidity, calcium deficiency, but also as a phosphate binder. Overall, calcium carbonate is the most calcium content of calcium, about 40%, while after the calcium into the body, the first will be the acid dissolution, will be Intestinal absorption, so the medical experts suggest that calcium carbonate is best to eat a meal in order to have enough stomach acid to calcium ions released, absorbed by the body. Used for making cement, ceramics, lime, calcium, toothpaste, dyes, pigments, mineral water, artificial stone, putty, neutralizers, catalysts, fillers, pharmaceuticals.
Can be used as rubber, plastic, paper, putty, primer, paint and ink industries such as fillers. Widely used in organic synthesis, metallurgy, glass and asbestos production. Also be used as industrial waste neutralizer, gastric and duodenal ulcer disease, antacids, acid poisoning antidote, sulfur dioxide emissions of sulfur dioxide elimination agent, dairy feed additives and oil felt a release agent. Also be used as a dentifrice, toothpaste and other cosmetic raw materials.
