Аннотация

The paper reports the data on the sensing properties of xCaO-(100-x)ZrO 2 (CSZ, x=9, 12 and 15 mol.%) and 8Y 2 O 3 -92ZrO 2 (YSZ) solid electrolytes, manufactured from nanosized low-agglomerated powder. Stabilized zirconia solid electrolytes (SE) were synthesized via the original co-precipitation technique and annealing at 1823K in air for 3 hours. Phase composition and conductivity of obtained ceramics was investigated via XRD and impedance spectroscopy techniques. Electromotive force (EMF) response on O 2 partial pressure was obtained at 966K for sensors with stabilized zirconia membranes. The data obtained was compared with Nernst equation. The impact of the precursor powder synthesis technique on electrical and sensing properties was discussed.
