Gas Sensing Property of Perovskite SrTi1−x Fe x O3−δ Fabricated by Thick Film Planar Technology
Planar sensor of SrTi1−x Fe x O3−δ , x = 0.4 and 0.6, with perovskite structure was fabricated on alumina substrate using thick film technology. Electrical resistance was measured as a function of thermal treatment conditions, atmosphere, time and temperature. Sensing property was also measured as a function of temperature and the gases of O2, CH4, CO, CO2, NO and NO2. The resistance of SrTi1−x Fe x O3−δ is lower than those of SrTiO3 or SrFeO3. TCR (temperature coefficient of resistance) of zero over 550 °C was measured for the composition of SrTi1−x Fe x O3−δ after thermal treatment at 1100 °C in air atmosphere only. The perovskite SrTi1−x Fe x O3−δ didn't show any response to CH4, CO, CO2, NO and NO2, but an excellent response and recovery characteristics with oxygen concentration.
