| Abstract | ||
| The Lanthanide carbonates, Ln2(CO3)3.nH2O of LnX3.nH2O (Ln= Dysprosium Dy, Holmium Ho, Cerium Ce and Europium Eu ; X-= Cl- or NO3-, n = 4-6) have been prepared by a novel synthetic method involving the reaction of aqueous solutions of the lanthanide metal ions with urea at ~850C for two hours. The reaction products were characterized via elemental analysis technique , infrared spectroscopy , volumetric and gravimetric analysis method. General reaction equations describing the formation of lanthanide carbonate compounds were proposed. | ||
