A solution of cobalt chloride having a gravity of 1.20 g/cm3 containing ammonium chloride was mixed while stirring with a solution of neodymium chloride and heated to 50° C. A stoichiometric equivalent quantity of sodium carbonate solution of 60° C. having a gravity of 1.05 g/cm3 was added to the mixed solution while stirring. The precipitates of cobalt carbonate and neodymium carbonate were obtained after reaction, 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 600° C. in hydrogen for 3 h, then crushed again and sieved by a 100 mesh sieve. The prepared cobalt powder contained 2.8% (wt.) neodymium.
