Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is an inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns.
Calcium nitrate is produced by applying nitric acid to limestone and then adding ammonia. It is known as a double salt, since it is comprised of two nutrients common in fertilizers which are high in sodium. The processed result also looks crystallized like salt. Calcium Nitrate is a colorless anhydrous salt that is used as a fertilizer, among other applications.
Calcium nitrate is obtained by treating limestone with weak nitric acid. It is also formed during the absorption of nitrogen oxide by milk of lime. Calcium Nitrate is also used in wastewater treatment, as a component in the manufacture of concrete, for medicinal purposes in cooling baths, and to store energy in solar power plants.
Calcium nitrate is mainly produced as a fertilizer, used for plant nutrition purposes, and for wastewater treatment. It is a source of both calcium and nitrogen, for plants.
Calcium nitrate is actively used to suppress the formation of odor in sewer networks and municipal wastewater treatment. The foul odor emanates primarily due to the release of hydrogen sulfide. Hydrogen sulfide production in sewers is associated with corrosion of concrete and metals, operational problems in wastewater treatment plants (WWTP), as well as with hygiene and odor problems.
Global Calcium Nitrate Market is projected to cross USD 11.0 billion by 2023, at a CAGR of over 5% during the forecast period. Demand for calcium nitrate is largely driven by high consumption of calcium nitrate fertilizers in emerging economies in Asia Pacific and Latin America.
