Widely Used In Pharmaceutical Industry And As Food Supplements
About Calcium Salts
Calcium salts are a class of chemical compounds that contain calcium ions (Ca2+) as cations. The calcium ion is a positively charged ion that plays essential roles in biological systems and has various industrial applications.
Common Uses And Applications
- Calcium Carbonate (CaCO3): Calcium carbonate is one of the most widely recognized calcium salts. It is commonly found in natural sources such as limestone, chalk, and marble. Calcium carbonate has many uses, including as a dietary supplement for calcium supplementation, as an antacid for heartburn relief, and as a filler in the production of paper, paints, plastics, and other industrial products. It is also a major component of agricultural lime used to improve soil quality and neutralize acidity.
- Calcium Chloride (CaCl2): Calcium chloride is a versatile calcium salt with various applications. It is commonly used as a de-icing agent to remove ice and snow from roads, sidewalks, and other surfaces. Calcium chloride is also used as a desiccant to control humidity and moisture in a variety of applications, such as drying agents and moisture-absorbing packs. It finds uses in food preservation, water treatment, and as a source of calcium in some industrial processes.
- Calcium Phosphate: Calcium phosphate is a family of compounds that include various forms such as calcium hydrogen phosphate (CaHPO4), dicalcium phosphate (CaHPO4), and tricalcium phosphate (Ca3(PO4)2). Calcium phosphate is a vital component of bones and teeth and is often used as a supplement in the food and pharmaceutical industries. It is also used as a mineral source in animal feed additives.
- Calcium Gluconate (C12H22CaO14) : Calcium gluconate is a calcium salt used for medical purposes. It is administered intravenously to treat conditions associated with low blood calcium levels, such as hypocalcemia or calcium channel blocker overdoses. Calcium gluconate is also used as a dietary supplement and in food and beverage fortification.
- Calcium Sulfate (CaSO4): Calcium sulfate exists in different forms, including anhydrous calcium sulfate (CaSO4), hemihydrate (calcium sulfate dihydrate, CaSO4·2H2O), and gypsum (calcium sulfate dihydrate). Gypsum is widely used in construction and building materials, including drywall and plasterboard. Calcium sulfate is also used as a coagulant in food processing, a soil conditioner in agriculture, and a filler in some industrial products.
