Cerium(III) selenate is an inorganic compound with the chemical formula Ce₂(SeO₄)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]
