Cerium salts

Cerium is the most abundant rare earth element and the only lanthanide with a readily accessible tetravalent state, which makes cerium(IV) a powerful single-electron oxidant. Cerium(III) salts serve as precursors for catalysts, phosphors and polishing oxides. Caesium salts, chemically distinct but grouped alongside, are used in density gradient centrifugation and as bases in coupling reactions. Molychem supplies ceric sulphate, ceric oxide, cerous nitrate and a range of caesium salts.
