Procedure

The filtrate solution containing the twice-purified lanthanum was acidified, using 200 mL of hydrochloric acid (37.5% by weight). Then a stoichiometric amount of oxalic acid in 1000 mL water was slowly added to the heated lanthanum solution (approximately 70° C.), resulting in a lanthanum oxalate precipitate. The precipitate was recovered by filtering the suspension using a sintered glass crucible of coarse porosity. The precipitate was washed with 3 liters of distilled water, dried and then heated in air to convert it to 150 g of lanthanum oxide (85% yield).
