Chandrashekhar A. Ladole*

ABSTRACT

Ferrite nanoparticles have significant applications in the field of heterogeneous catalyst and actively participated in developments of nano-chemistry, chemical and material chemistry that deals with the development and additional level of understanding. In this study strontium hexaferrite nanoparticles (SrFe12O19) were synthesised by microwave assisted solution combustion synthesis. The resultant powder was investigated by powder XRD, FT-IR TG-DTA, SEM analysis. The existence of the single-phase pervoskites structure with nano-crystalline size has been confirmed from the X-ray powder diffraction patterns. The stretching and bending vibrations of the metal cations are confirmed from the FT-IR spectra. The influence of ferrite synthesis condition, such as Sr/Fe molar ratio, pH value and time was investigated and powder was calcined at 500ºC for 5 hours.

Keywords: Strontium hexaferrite, nanoparticles, P-XRD, FT-IR, Microwave synthesis.
