In the present paper we have investigated synthesis of nickel ferrite (NiFe2O4) and cadmium substituted nickel ferrite (Ni1-xCdxFe2O4) powders with particles’ size in nanometer range using auto combustion technique as well as their sinterability. XRD analysis of the sintered samples confirmed the formation of single phase materials and the lattice parameter was increased with increase in cadmium concentration. It has also been observed that the estimated bulk densities of the materials decrease with increase in cadmium concentration, while they increase with the rise of sintering temperature.
