Calcium nitrate, also called Norgessalpeter (Norwegian Salpeter), is an inorganic compound with the formula Ca(NO3)2. This colorless 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 that 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. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate.

Calcium nitrate is used in wastewater pre-conditioning for odor emission prevention. The wastewater pre-conditioning is based on establishing anoxic biology in the wastewater system. In the presence of nitrate, the metabolism for sulfates stops, thus preventing the formation of hydrogen sulfide. Additionally easy degradable organic matter is consumed, which otherwise can cause anaerobic conditions downstream as well as odour emissions themselves. The concept is also applicable for surplus sludge treatment.

Concrete

Calcium nitrate is used in set accelerating concrete admixtures. This use of concrete and mortar is based on two effects. The calcium ion accelerates the formation of calcium hydroxide and thus precipitation and setting. This effect is used also in cold weather concreting agents as well as some combined plasticizers. The nitrate ion leads to the formation of iron hydroxide, whose protective layer reduces corrosion of the concrete reinforcement.

Latex coagulant

Calcium nitrate is a very common coagulant in latex production, especially in dipping processes. Dissolved calcium nitrate is a part of the dipping bath solution. The warm former is dipped into the coagulation liquid and a thin film of the dipping liquid remains on the former. When now dipping the former into the latex the calcium nitrate will break up the stabilization of the latex solution and the latex will coagulate on the former.

Cold packs

The dissolution of calcium nitrate tetrahydrate is highly endothermic (cooling). For this reason, calcium nitrate tetrahydrate is sometimes used for regenerable cold packs.

Molten salts for heat transfer and storage

Calcium nitrate can be used as a part of molten salt mixtures. Typical are binary mixtures of calcium nitrate and potassium nitrate or ternary mixtures including also sodium nitrate. Those molten salts can be used to replace the oil in concentrated solar power plants for heat transfer, but mostly those are used in heat storage.

Uses of Calcium Nitrate 

Used in agriculture as a fertilizer and in match manufacture as an oxidizing agent.

It is also used in the explosives and pyrotechnics industries.

It is used to make fireworks and incandescent lamp chimneys in the light industry.

Used as a raw material in making other nitrate compounds.

Used to improve the storage quality of crops reducing bitter pit in apples.
