The influence of 5, 10, and 15 wt % of yttrium oxide on gas sensitivity of tungsten oxide was studied. The prepared powders were mixed with a binder and printed onto the electrode surface using thick-film screen printing. Microstructure, electrical conductivity, and gas sensitivity of films were dep...
