However, it requires a high sintering temperature to obtain a fully dense body. In this study the effect of adding iron oxide to gadolinium-doped cerium (GDC) oxide to improve its sinterability and electrochemical performance was accessed. Doped GDC with different Fe molar concentrations (1, 3, 5 mol%) was successfully synthesized by a one-step aqueous precipitation method. Adding Fe 2 O 3 as a sintering aid increases the GDC densification and reduces its usual sintering temperature by ~300 °C. The microstructural and electrical properties of sintered pellets evidenced that using iron oxide as a sintering aid is a promising strategy to decrease sintering temperature of GDC.541-541openAccesscerium oxidesdoped materialsgadolinium additionsiron oxidessinteringtemperature range 0065-0273 kelectrochemistryResumo de eventos científicosaguardandohttps://orcid.org/0000-0003-0708-2021
