Abstract
Co – Zn ferrite nanoparticles have been synthesized using carboxylate- hydrazine precursor via thermal decomposition route. The prepared precursor Co 0.8 Zn 0.2 Fe 2 (PhAc) 3 (N 2 H 4 ) 3 was characterized by hydrazine, metal analyses, infrared spectral and thermal analyses. Using appropriate annealing conditions, Co 0.8 Zn 0.2 Fe 2 O 4 nanoparticles of average size 13 nm were synthesized by thermal treatment of the precursor. The nanoparticles were characterized by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), High Resolution Transmission Electron Microscope (HRTEM) and Selected Area Electron Diffraction (SAED) techniques. The details of synthesis and characterization of the nanoparticles are reported in this paper. DOI: http://dx.doi.org/10.5755/j01.ms.22.1.6278

Summary
During the last few decades, nanomaterials constitute an intensively studied class of materials; it is eminent that materials in the realm of nanometer scale show unexpected behaviour with respect to its physical and chemical properties. Hydrazine being a fuel supports combustion and lowers the decomposition temperature of the metal complexes [6, 7] Many such thermal decomposition methods are employed for the synthesis of metal and mixed metal oxides using metal carboxylate and carboxylatohydrazinates complexes of oxalate [8], formate [9], acetate and propionate [10] malonate, succinate and itaconates [11, 12], maleate and tartrate [13, 14] malate [15] and fumarate [16 – 18] have been studied. Among the large number of techniques employed for the synthesis of oxides, thermal treatment is found to be unique and highly versatile It is an easy and fast process which yields highpurity, homogenous, crystalline oxides in a short time and with less energy. We report a novel method of synthesis of Co – Zn ferrites using the inorganic precursor Co0.8Zn0.2Fe2(PhAc)3(N2H4) and detailed structural characterization of these particles
