실험 절차

A solution of cobalt chloride having a gravity of 1.10 g/cm3 was mixed homogeneously with a solution of samarium nitrate having a concentration of 94 mg/ml in a volume proportion of 150:1. The mixed solution was heated to 70° C. A solution of ammonium oxalate having a gravity of 1.15 g/cm3 and a pH value of 5 was added to the mixture while stirring. The quantity of the added ammonium oxalate was 1.7 mole equivalent per mole equivalent cobalt chloride and samarium nitrate. The precipitates of cobalt oxalate and samarium oxalate were obtained after reaction, then filtrated in a vacuum filtrator to remove the mother liquid, washed by distilled water of 90° C. for 6 times, dried at 200° C., crushed and sieved by a 20 mesh sieve, reduced at 530° C. in hydrogen for 4 h, crushed again and sieved by a 100 mesh sieve.
