A 4.43mol/L ammonium bicarbonate solution was prepared with ammonium bicarbonate and ammonia water,under the room temperature,neodymium nitrate solution and hydrogen peroxide were added to the ammonium hydrogen carbonate solution,then a purple peroxide carbonate neodymium precipitation formed,the precipitation was dealed with washing,filtering and drying,and burning at 900-1200℃ for 4 hours,large particles of neodymium oxide obtained,the product was characterized by XRD,particle size,liquidity and SEM.
