Procedure

A solution of cobalt chloride having a gravity of 1.05 g/cm3 was mixed with a solution of cerium nitrate and heated to 35° C., followed by adding, while stirring a solution of ammonium oxalate having a gravity of 1.03 g/m3 and a pH 3. The quantity of ammonium oxalate added was 1.5 mole equivalent per mole equivalent of cobalt chloride and cerium nitrate. The precipitates of cobalt oxalate and cerium oxalate were obtained after reaction and 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 550° C. in hydrogen for 3 h, then crushed again and sieved by a 100 mesh sieve. The prepared cobalt powder contained 0.5% (wt.) cerium.
