| Hazard Information | Back Directory | [Uses]
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. | [Physical properties]
Hexahydrate is a colorless crystal; hygroscopic; loses water on heating— three molecules of water of crystallization expelled at 150°C; decomposes at 200°C; readily dissolves in water, alcohol, and acetone. | [Preparation]
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. | [Flammability and Explosibility]

II | [Safety Profile]
Poison by intravenous
and intraperitoneal routes. Moderately toxic
by ingestion. Experimental reproductive
effects. See also CERIUM COMPOUNDS
and NITRATES. When heated to
decomposition it emits toxic fumes of NOx. | [Toxicity]
LD50 in rats: 290 mg/kg i.p.; 4.2 g/kg orally (Bruce) |
