Cerium sulphide (Ce 2 S 3) is likely to replace cadmium in red pigments for containers, toys, household wares and crates, since cadmium is now considered environmentally undesiderable. Other uses of cerium are in flat-screen televisions, low-energy light bulbs and magnetic-optic compact discs, in chromium plating. The ceric ion, Ce(IV) is more easily hydrolysed than the lanthanide (III) ions and therefore precipitates as a salt upon treatment with an oxidizing agent such as KMnO 4. Pure cerium is available through the electrolysis of a mixture of molten CeCl 3 and NaCl (or CaCl 2 ) in a graphite cell which acts as cathode using graphite as anode.
