摘要：

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 degrees 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 degrees C.
