Anwendungen & Verwendung
Verwenden
Cerium trinitrate is used for separation of Ce from other rare earths; catalyst in hydrolysis of phosphoric acid esters; mixture with Th(NO3)4 (1:99) formerly used in manufacture of incandescent mantles.
Herstellung & Synthese
synthetische
Cerium(III) nitrate may be prepared by the action of nitric acid on a cerium(III) salt, followed by crystallization: Ce2(CO3)3 + 6HNO3 → 2Ce(NO3)3 + 3CO2 + 3H2O.
