HCID 168924Lanthanum carbonate anhydrous

Procedure

Adding 7 liters of the above magnesium bicarbonate solution into a reactor containing 1.6 liters of lanthanum chloride solution (0.92 mol/L) to react for 2 hours, and controlling the reaction temperature at 50° C. and the pH value of mother liquor at 6.5, the rare-earth (RE) ions can be completely precipitated, and then lanthanum carbonate is obtained after filtration.
