Solid State Synthesis of the SrTiO3 Nano-particle

Recent studies have shown the ability to synthesize peroviskite materials through solid state chemical reaction. In previous work at the University Annamalai Naga, a specific peroviskite SrTiO3 (STO) was created through solid state reaction between strontium carbonate and, titanium dioxide powders that were homogenously mixed and then sintered until completion of the reaction. The sintered powder was characterized by X-ray diffraction (XRD) and shown to be a perovskite structure without evidence of additional phases. This work specifically reports on the reproducible solid state reaction procedure developed at the University of Arkansas for the production of STO powder, characterization of formed compounds. The phase transformation was confirmed by X-ray diffraction (XRD) analysis and Dispersive X-ray Spectrometry (EDX). Using the procedure 99.9% pure STO powder was produced, with the compound synthesized having similar cubic structure to STO references. EDX characterization agreed with XRD results and showed the formation of a fine powder necessary for pulsed laser deposition (PLD) targets. Future work can be done in research of the solid state synthesis of more materials from the peroviskite group and in optimization and creation of inexpensive pulse laser deposition targets
