Cerium has no biological role but is said to stimulate the metabolism. The British Pharmaceutical Codex from 1907 indicates that cerium nitrate ["cerii nitras", Ce(NO3)3] was used to treat dyspepsia, pyrosis, and vomiting (especially "vomiting of pregnancy") in doses of 0.05-0.3 g ("1 to 5 grains") and that cerium salts have pharmacological properties similar to those of bismuth. The oxalate ["cerii oxalas", Ce2(C2O4)3.9H2O] was also used for "chronic vomiting, especially the vomiting of pregnancy." The doses were 0.6 g, three times a day for several days if necessary.

Cerium - Chemistry with Mr. Olson

My History!!

Cerium was discovered in Sweden by Jöns Jakob Berzelius and Wilhelm von Hisinger, and independently in Germany by Martin Heinrich Klaproth, both in 1803. Cerium was so named by Berzelius after the asteroid Ceres, discovered two years earlier (1801).


My Jobs

  • component of misch metal, used in the manufacture of pyrophoric alloys for cigarette lighters, etc.
  • the oxide is an important constituent of incandescent gas mantles and is a catalyst in "self-cleaning" ovens. In this application it is incorporated into oven walls to prevent the collection of cooking residues
  • the sulphate is used extensively as a volummetric oxidizing agent in quantitative analysis
  • used in the manufacture of glass, both as a component and as a decolourizer
  • the oxide is used as a glass polishing agent instead of rouge, as it is much faster at polishing glass surfaces
  • used in carbon-arc lighting with other rare-earth elements, especially in the motion picture industry
  • used as a catalyst in petroleum refining
  • metallurgical and nuclear applications
