Calcium is a chemical element with the symbol Ca and atomic number 20.
It is a soft, malleable, and ductile metal in the earth's crust and is the fifth most abundant element by mass after oxygen, silicon, aluminum, and iron.
Calcium is essential for the functioning of many biological processes, including the development and maintenance of bones and teeth, the regulation of muscle and nerve function, and the blood clotting process.
In the chemical industry, calcium is used in a variety of applications due to its unique properties.
It is a fundamental component of many chemical reactions and is used in the production of a range of products, including fertilizers, cement, glass, and paper.
One of the most common uses of calcium in the chemical industry is in the production of calcium oxide, also known as lime.
Lime is a versatile chemical compound that is used in a variety of applications, including water treatment, soil conditioning, and the production of paper and cement.
Lime is also used as a flocculant in water treatment, which helps to remove impurities and improve water quality.
Another common use of calcium in the chemical industry is in the production of calcium carbonate, which is used as a filler in the production of paper and as a constituent in the manufacture of some types of plastics.
Calcium carbonate is also used as a stable form of carbon dioxide in the food industry and as a supplement in some pharmaceutical products.
Calcium is also used in the production of calcium chloride, which is used as a flocculant in water treatment, as a fire retardant, and as a deicing agent.
Calcium chloride is also used in the production of PVC, which is a widely used plastic in construction and in the manufacture of a variety of consumer goods.
Calcium is also used in the production of calcium sulfate, which is used as a coagulant in water treatment, as a soil conditioner, and as a filler in the production of paper.
Calcium sulfate is also used in the production of plaster of Paris, which is a commonly used material in the construction industry.
