Zirconium nitrate

Chemical properties

white, very hygroscopic crystal(s) [MER06]

General Description

Zirconium(IV) nitrate is a white crystalline solid. Zirconium(IV) nitrate is soluble in water. Zirconium(IV) nitrate is noncombustible, but Zirconium(IV) nitrate will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving Zirconium(IV) nitrate. Zirconium(IV) nitrate is used as a preservative.

Reactivity Profile

Mixtures of metal/nonmetal nitrates, such as Zirconium(IV) nitrate, with alkyl esters may explode owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Dissolves in water to give an acid solution.

Health Hazard

Has only a mild pharmacological action. Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation.

Safety Profile

Moderately toxic by inhalation and ingestion. A powerful oxiQzer. When heated to decomposition it emits toxic fumes of NOx. See also NITRATES and ZIRCONIUM COMPOUNDS.
