چکیده انگلیسی
This paper reports the preparation of nanometric powders of 3.5 mol% Y2O3-doped ZrO2, with controlled microstructure, by the spray pyrolysis process, assisted by ultrasonic atomizer, at relatively low temperature. As-prepared powders were found crystalline and consisted of dense and chemically homogeneous spherical particles. Conventional sintering at 1500 °C for 2 h in air yields dense ceramics of 83 nm of average grain size. The electrical properties of electrode/electrolyte interface were determined by impedance spectroscopy measurements before, during and after thermal ageing for 2000 h at 700 °C in dry air. The effect of thermal ageing on the electrical responses of the ceramic and interfaces with platinum electrodes was investigated.
