AB  - Systematic analysis of electrical characteristics of BaCe0.75In0.25O3-δ (BCI25) sintered sample was performed in a
dry and a wet argon atmosphere in the 250 ◦C–700 ◦C temperature range. The water vapor sensing properties of
BCI25 porous film and its response and recovery times were investigated under different conditions of temperature
and water vapor concentration. The 30 μm thick film obtained from the powder calcined at 1050 ◦C
exhibited sensitivity comparable to that of the sintered sample with a significantly shorter response and recovery
times. While the sensitivity of the film gradually decreased with a decrease in partial pressure of water vapor (p
(H2O)), a noticeable sensitivity was still observed at p(H2O) of 200 Pa. Decrease in conductivity depended
logarithmically on the partial pressure of water with the slope of 0.52 that is close to the theoretical value. After
several cycles, the reusability test proved an almost unchanged ratio between the impedance value in the dry and
the wet Ar atmosphere (p(H2O) = 2.34 kPa), which implied that BCI25, having good stability and sensitivity, is a
promising high-temperature humidity sensor.
