Description
A white, deliquescent solid that is a strong oxidizing agent. Calcium nitrate was first produced commercially in Notodden, Norway in 1905. It is used in pyrotechnics, explosives, and match heads. Calcium nitrate has been identified as a deleterious accretion in wall paintings (Piqué et al 1992). The efflorescence also occurs when manure or other nitrogeneous compounds contact limestone in a dry environment.
Synonyms and Related Terms
calcium dinitrate; lime nitrate; nitrocalcite; lime saltpeter; Norwegian saltpeter (Norgessalpeter); air saltpeter; calciumnitrat (Dan.); Kalksalpeter (Nor.); CalciNit
Risks
