Cerium (Ce) - Periodic Table (Element Information & More)

WebCerium is a Block F, Period 6 element. It is the most abundant of the rare earth elements, and is found in minerals bastnasite, synchysite, hydroxylbastnasite, sallanite, monazite, … Cerium occurs naturally as oxides, always as a mixture with other rare-earth elements. Its principal ores bastnaesite and monazite. After extraction of the metal ions into aqueous base, Ce is separated from that mixture by addition of an oxidant followed by adjustment of the pH. This step exploits the low solubility of CeO2 and the fact that other rare-earth elements resist oxidation. Cerium(IV) oxide is formed by the calcination of cerium oxalate or cerium hydroxide.
