dc.description.abstractLas perovskitas basadas en titanato de bismuto y sodio, Bi0.5Na0.5TiO3 (BNT), son implementadas en materiales piezoeléctricos libres de plomo. A pesar de que el BNT fue descubierto hace cinco décadas, no se tiene aún claridad en ciertos temas cruciales como su complejidad estructural y las modificaciones que experimenta cuando se combina con otras perovskitas. En este trabajo se estudió la influencia de la adición de BaTiO3 (BT) y SrTiO3 (ST) sobre las propiedades estructurales y microestructurales del Bi0.5Na0.5TiO3 (BNT), usando sol gel como método de síntesis.La caracterización de los polvos cerámicos se realizó por espectroscopia infrarroja y Ramman, difracción de rayos-X y Microscopía electrónica de barrido, lo que permitió concluir que la adición de BT/ST modifica los enlaces, genera coexistencia y transición de fase y confirma la existencia de un contorno de fase morfotrópico.spa
dc.description.abstractPerovskites based on bismuth sodium titanates, Bi0.5Na0.5TiO3 (BNT), are incorporated into lead-free piezoelectric materials. Although BNT was discovered five decades ago, many aspects such as the structural complexity and the modifications produced when it is combined with other perovskites are not clearly understood. We studied the structural and microstructural properties of BNT upon addition of BaTiO3 (BT) and SrTiO3 (ST) during sol-gel synthesis. We characterized the ceramic powders by infrared and Raman spectroscopy, X-ray diffraction and scanning electronic microscopy. The addition of BT/ST modified the bonds, generating coexistence and phase transition and confirmed the existence of a morphotropic phase boundary. eng
