Abstract: Zinc ferrite nanoparticles were prepared via thermal treatment of their mixed hydroxides at 400°C-600°C. The mixed hydroxides were co-precipitated from their nitrates solutions using NaOH as precipitating agent. The effects of pH and calcination temperature on the microstructure of the prepared system were studied using X-ray powder diffraction and Mossbauer spectroscopy. The crystallite sizes of the synthetic ferrite ranges between 12-48 nm respectively. The crystallite size of each sample was found to be strongly dependent on the calcination temperature and pH. Moreover, the Mossbauer profile of Zinc ferrite phase is discussed in terms of the particle size and the measuring Mossbauer temperature.
