Sol Gel Synthesis and Characterization of Strontium Titanates

Abstract

Pure strontium titanates have been successfully fabricated in this work via sol gel route. The obtained powders were calcined at various temperatures and effects of calcination and sintering on phase development, crystallite size, lattice parameters, microstructure etc. were investigated by XRD and SEM techniques. The development of phase with temperature has been investigated using DTA/TG technique. The dielectric and electrical parameters were analyzed and effects of temperature and frequency variation on these parameters were studied.
