Resumo
The effect of a microwave-assisted hydrothermal (MWH) treatment on the structural,
thermal, and electrical properties of NiO/ZrO2:8 mol%Y2O3(YSZ)/CeO2 (60/20/20 wt.%)
composite was investigated. Powders were synthesized by a hydroxide coprecipitationimpregnation technique, in which Ni and Ce oxides were coprecipitaed in a suspension containing
YSZ. Simultaneous thermogravimetry and differential thermal analysis revealed that MWH
treatment promotes the crystallization of coprecipitated phases. X-ray diffraction analysis was used
for phase identification and the calculated lattice parameters indicated the formation of YSZ:CeO2
solid solution during sintering. Impedance spectroscopy measurements showed that the electrical
properties of the composite samples were not significantly affected by the MHW.
