Iron manganite (FeMnO3) powder with a cubic (bixbyite,
−
Ia3) crystal structure was obtained by a solid state
reaction. Thick film paste (powder+organic vehicles) was screen printed on alumina substrate with test interdigitated
PdAg electrodes. Significant porosity (60.6%) composed of macropores (larger than 100 nm) was
determined by Hg porosimetry, changing only slightly from the first extrusion run indicating a stable pore
system. Hg porosimetry evaluation of thick film samples enabled estimation of true textural parameters of the
thick film compared to powder. Impedance response of the thick film sensor was monitored in a humidity
chamber in the relative humidity (RH) range 30–90%, at room temperature (25 °C) and frequency range from
42 Hz to 1 MHz. At 100 Hz the impedance reduced from 10.41 MΩ for RH 30% to 0.68 MΩ for RH 90%. Analysis
of complex impedance using an equivalent circuit showed the dominant influence of grain boundaries. The
sensor response and recovery was ...fast (several seconds) and a relatively low hysteresis value of 2.8% was
obtained.
