Europium(III) carbonate is an inorganic compound with the chemical formula Eu2(CO3)3.




Preparation


Europium(III) carbonate can be obtained by mixing and heating an aqueous solution of ammonium carbonate and europium(III) chloride. 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. Other preparation methods include the thermal decomposition of europium(III) acetate and the reaction of a suspension of europium(III) oxide in water and supercritical carbon dioxide.




Chemical properties


Europium(III) carbonate is soluble in acid and releases carbon dioxide:

Eu2(CO3)3 + 6 H+ → 2 Eu+3 + 3 H2O + 3 CO2↑
Europium(III) carbonate decomposes at high temperatures to form europium(III) oxide:

Eu2(CO3)3 → Eu2O3 + 3 CO2↑
