  • Abstract
    The influence of doping by gallium (0-10 wt.%) on gas-sensing characteristics of In2O3-based gas sensors has been studied. In2O3-based ceramic was prepared by sol-gel technology. Ozone, CO, CH4 and H2 were used as tested gases. The addition of Ga into the In2O3 matrix was found to be effective in increasing sensor response to ozone and improvement of sensor response selectivity. It was assumed that this improvement was connected with optimization of In2O3 ceramics structure.
