Europium(III) carbonate is an inorganic compound with the chemical formula Eu2(CO3)3.
Europium(III) carbonate can be obtained by mixing and heating an aqueous solution of ammonium carbonate and europium(III) chloride. [2] A saturated carbon dioxide ammonium carbonate solution (obtained from the reaction of hydrochloric acid and ammonium carbonate solution) can also precipitate europium carbonate from a europium salt solution. [3] Other preparation methods include the thermal decomposition of europium(III) acetate [4] and the reaction of a suspension of europium(III) oxide in water and supercritical carbon dioxide. [5]
Europium(III) carbonate is soluble in acid and releases carbon dioxide: [1]
Europium(III) carbonate decomposes at high temperatures to form europium(III) oxide:
