Abstract
We have investigated on the synthesis of Ba1 − xSrxTiO3 (BST, x = 0.0–1.0) solid solution at low temperature by a sol-gel method using precursor solutions of Ba(OC2H5)2, Sr(OC2H5)2, and Ti(OCH(CH3)2)4 dissolved in 2-methoxyethanol. Crystalline BST solid solution monolithic gels were obtained as dried at 90°C. Crystalline fraction of BST gels increased with increasing concentration of the precursor solution and increasing amount of the hydrolysis water used. Ba0.4Sr0.6TiO3 (x = 0.6) gels from a precursor solution of 0.5 mol/l with hydrolysis water of H2O/Ti = 50 crystallized during aging at 30°C.
