Description générale

Lanthanum(III) nitrate hydrate is a white crystalline solid that is highly soluble in water. It is also utilized in various fields such as catalysts, ceramics, and as a source of lanthanum ions in chemical synthesis.

Application

Lanthanum(III) nitrate hydrate can be used:
  • As a starting material to synthesize lanthanum zirconate nanoparticles.
  • As a precursor to prepare luminescent lanthanum-tricarboxytriphenylamine (La-TCA) coordination polymer nanosheets.
  • To fabricate perovskite oxide-type LaFeO3 dendrites for chemical sensors.
  • To synthesize LaMnO3 perovskite catalysts by using citric acid sol–gel method and La0.6Sr0.4MnO3 perovskites via coprecipitation method. The LaMnO3 perovskite catalysts has used for the oxidation of propane for emission control of hydrocarbon volatile organic compounds.

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.
