Descripción general

Cerium (III) nitrate hexahydrate is the most common form of cerium nitrate. It is a white-to-yellow crystalline salt, and it is highly soluble in water, alcohol, and acetone, although solutions can appear slightly hazy. Like many trivalent metal nitrates, cerium (III) nitrate hexahydrate has a low-melting point of only 57 °C and thermally decomposes at low temperatures too, beginning at 190 °C and proceeding rapidly at 280 °C with complete decomposition at 390-400 °C.

Aplicación

Cerium (III) nitrate hexahydrate is widely used as a source of cerium, especially in the synthesis of micro- or nano-structured ceria (cerium oxide). Because of its high solubility and low decomposition temperature, cerium (III) nitrate hexahydrate is an ideal reagent for hydrothermal reactions, sol-gel processing, and co-precipitation and calcination reactions.

Ceria is one of the best studied materials-platforms for catalysis and solid oxide fuel cells. Consequently scientists have developed well-controlled synthetic protocols using cerium (III) nitrate hexahydrate for preparing ceria nanoparticles including nano cubes, nanotubes, and nanorods. The tailorable synthesis facilitates using ceria as a catalyst support, for example leveraging the porosity of the microstructure to impregnate metals and metal alloys, or for example synthesizing ceria-based materials like ceria-zirconia.

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.
