Low-temperature sol-gel synthesis of modified nickel ferrite

Abstract

A low-temperature method has been developed for preparing nickel ferrite doped with cobalt and copper (Ni 0.9 Co 0.1 Cu 0.1 Fe 1.9 O 4 − δ ). This method provides the target product at 170–200°C with nanosized particles. The role of ammonium nitrate in the considerable reduction of ferrite synthesis temperature was studied.
