SrBi2Ta2O9 precursor solutions have been prepared by sol-gel using, as reactives, tantalum ethoxide and strontium and bismuth 2-ethyl-hexanoates. These compounds were disolved in 1,3-propanediol as majoritary solvent. The resulting solutions had low hydrolysis and condensation, thus making possible their manipulation and storage in atmospheres with moisture. Films deposited from these solutions were crystallised at 750ºC, developing, as majoritary phase, the SrBi2Ta2O9 layered perovskite. Electric poling of these films indicates a moderate ferroelectric response with values of remanent polarisation of Pr~1μC/cm2.<br><br>Se han preparado por sol-gel soluciones precursoras de SrBi2Ta2O9, utilizando como reactivos el etóxido de tán...
