Abstract

Nanosized strontium titanate (SrTiO3) was synthesized from strontium titanyl oxalate hydrate, SrTiO(C204)24H20 (STO) precursor employing microwave heating technique. STO precursor was characterized by Thermogravimetry (TG) and differential thermal analysis (DTA) techniques prior to the heat treatment in conventional and microwave heating system. STO precursor heated in microwave heating system in air at 773 K for 30 min yielded pure cubic SrTiO3. The product obtained by heating of STO precursor in the same system at 973 K for same duration was, however, much more crystalline. Experiments repeated in conventional furnace showed that SrTiO3 was formed above 973 K. SrTiO3 powder obtained was characterized by X-ray diffraction (XRD) and Transmission electron microscopy (TEM) techniques. TEM study shows that the particles of SrTiO3 are nearly spherical in shape and the particle size of SrTiO3 powder varies between 28 and 68 nm.
