Thulium(III) selenate is an inorganic compound, with the chemical formula Tm2(SeO4)3. It can be obtained by reacting a thulium(III) oxide and selenic acid solution and crystallizing it.[1] It crystallises with ammonium selenate in an aqueous solution to obtain NH4Tm(SeO4)2·3H2O.[2]
Thulium(III) selenate decomposes at high temperatures and passes through Tm2(SeO3)3 to finally obtain the oxide Tm2O3.[3]
