• Description: Calcium nitrate has the molecular formula of Ca(NO3)2 and the molecular weight of 164.0935 g/mol. Its CAS number is 10124-37-5. Calcium nitrate may be prepared by the reaction of nitric acid with calcium carbonate or calcium sulfide: CaCO3 + 2HNO3 ? Ca(NO3)2 + CO +H2O CaS + 2HNO3 ? Ca(NO3)2 +H2S It is very soluble and forms a tetrahydrate, Ca(NO3) 2·4H2O if the solution is evaporated to dryness. The CAS number of the anhydrate is 10124-37-5 while that of the tetrahydrate is 13477-34-4. As with the beryllium nitrate salts, variation of the nitric acid concentration affects the type of hydrate produced. The trihydrate is known (CAS number 10124-37-5) but not the monohydrate. The anhydrate is a white cubic crystal that is hygroscopic; its density is 2.504 g/cm3 and it melts at 561°C. This salt is highly soluble in water and also dissolves in alcohols and acetone. The tetrahydrate melts in its own waters of hydration at 42.7°C and loses 4H2O molecules at 132°C. It decomposes to form nitrogen oxides and CaO similar to the behavior of the other alkaline earth nitrates. The anhydrous salt is soluble at 121.2 g/100 ml at 20°C and 271.2 g/100 ml at 40°C.
• Physical properties: White cubic crystal; hygroscopic; density 2.50g/cm3; melts at 561°C; highly soluble in water; also dissolves in alcohols and acetone.
• Uses: Calcium nitrate is mainly used as a component in fertilizers. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence in places where manure contacts limestone (or concrete) in a dry environment such as caverns or stables.Calcium nitrate is used in explosives, matches and pyrotechnics. Other applications are in the manufacture of incandescent mantle; and as an additive to diesel fuel for corrosion inhibition.This calciumnitrate is useful as an oxidizer but its hygroscopic nature, results in extreme deliquescence in air. Calcium nitrate is mainly used as a flocculent in rubber latex and in refrigerant manufacture. And it is also employed in oil exploratory wells and sewage treatment. In agriculture, it is used in hydroponic culture and as a fast-effective fertilizer for acid soil. It can also be used to make fireworks, to produce explosives in national defense industry, and to paint negative poles in the electronic instrument industry. It is also a raw material in making other nitrates. It is this usage that calcium nitrate finds most of its employment in industry, other than its use in agriculture. Calcium nitrate is a strong oxidizing agent. Mixing it with organic substances such as fuel oil or hydrocarbons or other oxidizable compounds can cause an explosion. Calcium nitrate has been evaluated as a component for heat storage devices. Calcium nitrate [Ca(NO3)2] is known as Norwegian saltpeter. It is a strong oxidizer (because of the NO3) that is flammable in the presence of organic materials (such as hands). It explodes when given a hard shock. It is used in fireworks, matches, and fertilizers. In explosives, fertilizers, matches, pyrotechnics; manufacture of incandescent mantles, radio tubes, HNO3; corrosion inhibitor in diesel fuels.
