Abstract

Iron manganite (FeMnO3) powder with a cubic (bixbyite,−Ia3) crystal structure was obtained by a solid statereaction. Thick film paste (powder+organic vehicles) was screen printed on alumina substrate with test interdigitatedPdAg electrodes. Significant porosity (60.6%) composed of macropores (larger than 100 nm) wasdetermined by Hg porosimetry, changing only slightly from the first extrusion run indicating a stable poresystem. Hg porosimetry evaluation of thick film samples enabled estimation of true textural parameters of thethick film compared to powder. Impedance response of the thick film sensor was monitored in a humiditychamber in the relative humidity (RH) range 30–90%, at room temperature (25 °C) and frequency range from42 Hz to 1 MHz. At 100 Hz the impedance reduced from 10.41 MΩ for RH 30% to 0.68 MΩ for RH 90%. Analysisof complex impedance using an equivalent circuit showed the dominant influence of grain boundaries. Thesensor response and recovery was fast (several seconds)...
