Infobox references

Cerium(III) selenate is an inorganic compound with the chemical formula Ce
2(SeO

3. It can be obtained by reacting selenic acid and cerium(III) carbonate, and the solvent is evaporated to precipitate crystals.[2] The double salt CsCe(SeO4)2·4H2O can be obtained from mixing cerium(III) selenate and cesium selenate in an aqueous solution, and then evaporating and crystallizing the solution.[3]
