A new technique for preparing metal/ferrite composite powder by the pyrolysis of ferrous oxalate and nickel oxalate powders derived from coprecipitation has been proposed. The technique was carried out as follows ; pyrolysis of the coprecipitated powder under NH<SUB>3</SUB> gas flow and subsequent pyrolysis of mixtures of ferrite and (Fe<SUB>3</SUB>Ni)N powders under N<SUB>2</SUB> gas flow. (Ni-Fe)/Fe<SUB>3</SUB>O<SUB>4</SUB> composite powder was prepared by heating the coprecipitated powder of NiC<SUB>2</SUB>O<SUB>4</SUB>/FeC<SUB>2</SUB>Oa=0. 5-r2. 0 (molar ratio) at 350°C for 1h in NH<SUB>3</SUB> gas, followed by heating at 500°C for 1 h in N<SUB>2</SUB> gas. It was found that the thermal stability of (Ni-Fe)/Fe<SUB>3</SUB>O<SUB>4</SUB> composite powder was affected by the composition of (Ni-Fe)alloy in the composite powder.
