Perovskites with formula A1-xSrxBO3-δ (A = La, Nd, Sm; B = Fe or Co) have been synthesized by solid state reaction method and have been studied as materials for oxygen sensor application. The obtained powders were used for making thick film pastes that were later screen printed as sensing electrodes on yttria stabilized zirconia (YSZ) substrates. Sensing electrodes were exposed to low concentration oxygen gas at elevated temperatures. Measurements of the electromotive force of electrochemical cells with the fabricated electrodes were carried out as a function of temperature. The investigation indicated that all of the synthesized materials show Nernstian behavior in a relatively wide temperature range, although the most promising for oxygen electrochemical sensor application is strontium doped samarium cobaltite.

ABSTRACTExperiments were conducted to determine the mechanical characteristics of an yttria-stabilized tetragonal zirconia containing 3 mol % Y2O3. Specimens were pulled in tension at elevated temperatures over a range of strain rates. It is demonstrated that this material exhibits good superplastic ductility, with tensile elongations >100% when the tests are conducted at low strain rates. Internal cavities are formed during deformation and it is shown that the cavitated area decreases with decreasing strain rate. At fast strain rates, of the order of 10−3 s−1, the cavities tend to link preferentially in a direction perpendicular to the tensile axis.
