Resumen

The present work deals with mullite (Al₂O₃·2SiO₂) as a potential material for application as solid electrolyte in high-temperature electrochemical devices. The structure and preparation of mullite and the design of mullite-based oxygen sensors are described. The predominantly ionic conduction of mullite is characterized by means of the parameter P_e' (t_ion=0.5) of electronic conductivity and the temperature dependence of the ionic transference number t_ion. It is confirmed that mullite features ionic conductivity superior to that of the usual CaO-stabilized ZrO₂ solid electrolytes at temperatures from 1400 to 1600°C.
