Microwave-Assisted Synthesis and Characterization of Strontium Titanate Nanoparticles

Abstract

In microwave heating the total heating cycle time very less with comparison to conventional heating. This study is carried out to investigate the effect of the time duration of the calcination temperature on the structural properties of SrTiO3 Ceramic powder. The present powder was synthesis by solid-state reaction method. The powders were calcined at a temperature of 1200oC at four different durations, namely (20, 30, 40, and 50 minutes) using microwave sintering systems. The phase structure was investigated by using XRD along with Rietveld refinement analysis. A single-phase with a cubic structure was obtained in all calcined samples.  The images and the particle size distribution of the calcined powder are carried out by using FE-SEM and particle size analyzer, respectively. The results show that the particle size has increased with an increase of the duration time, and the powder agglomerations’ has taken place for the calcined at 50 minutes duration.
