dc.description.abstractMidiendo la resistencia eléctrica del electrolito sólido NaI-AgI, se mostró que al adicionar NaI al AgI se estabiliza la transición de la fase conductora iónica (β-AgI) a la fase superiónica (α-AgI) a 420 K al incrementar la temperatura. La conductividad iónica en la transición β → α del AgI aumenta varios órdenes de magnitud. Para simular esta transición, se consideró un modelo fenomenológico basado en una densidad de energía libre, siendo la concentración de defectos en equilibrio (n) el parámetro de orden e interpretando éste como el inverso de la resistencia R. Los datos experimentales se ajustaron muy bien al modelo propuesto.spa
dc.description.abstractElectrical resistance measurements of NaI-AgI solid electrolyte showed that adding NaI to AgI stabilizes the transition from conducting ionic phase (β-AgI) to the superionic (α-AgI) at 420 K with increasing temperature. The ionic conductivity at the β → α transition of AgI increases by several orders of magnitude. Considering a phenomenological model based on a free energy density was fitted the abrupt jump of ionic conductivity. In this model, the equilibrium defect concentration (, R is the resistance) is the order parameter. Better results are achieved for the order parameter.eng
