Doping SnO₂ with Sb was investigated in relation with sensitization of a SnO₂-based thick film sensor for C ₂H₄O gas. With Sb doping by 0.05 or 0.1%, resistances of the films lowered drastically, suggesting an optimum Sb doping of about 0.05%. When loaded with La₂O₃(0.5 wt.%), Sb(0.05 at.%)-SnO ₂ gave sensor response (R_air/R_gas) exceeding 4 to 1 ppm C₂H₄O at 250°C. Although this performance was almost comparable with that exhibited by the device using neat SnO₂, the electrical resistance of the former device was still at 10⁶ Ωat 250°C and appeared to afford further loading with Pt or Pd for promotion of rates of response and recovery.
