Abstract

• Magnesium-Zinc Ferrite, Mg1-xZnxFe2O4 (where x=0.50) was prepared by flash-combustion technique. The sample was characterized by XRD, SEM and FTIR-spectroscopy to study the structural, microstructural and vibrational characteristics. XRD pattern revealed that the sample analogous to cubic structure with the lattice parameters a=b=c=8.3512 Å. The crystallite size was obtained as 47.96 nm and showed that the sample was the nanosized material. SEM micrograph showed that the grain shape of the sample was spherical with the grain sizes of 0.20 μm – 0.50μm. Vibrational characteristics of tetrahedral site and octahedral site atoms were studied from the collected FTIR spectrum. Temperature dependent electrical conductivity and humidity sensitive electrical properties of the sample were observed for the applications of humidity sensing materials.
