Fabrication and study of the structural and spectral properties of the composites (y) Mn0.6 Zn0.4 Fe2O4 + (1-y) PZT prepared by the powder technology method

Abstract

Ferrite-ferroelectric composites holds following chemical formula (y) Mn0.6 Zn0.4 Fe2O4 + (1-y) PZT with different weight rations (y=0.15, 0.30 and 0.45) are prepared by the powder technology method at annealing temperature (1000 °C) for (12hrs). The structural properties are also studied representing by the lattice constants (a, c), particle size (Dt), apparent density (ρa), and X-ray density (ρx). It has been shown that increasing the concentration of the ferrite phase contributes to an increase in the lattice constant, apparent density and X-ray density which in turn contribute in decreasing porosity that plays a role in improving the physical properties of the samples as well as the weight ratios of the mixture after the final sintering with reference to x-ray diffraction technique. In addition, the spectral properties were also studied represented by the vibration force constant and regions of optical absorption in terms of IR technique.
