Abstract

Recently, research into the characteristics of semiconductor metal oxides that are stable at high temperatures with a view to providing reproducible detection of oxygen and reducing gases has intensified. First of all, there is a discussion of the specifics relating to these materials, for example the reduction of the effects of grain-boundary barriers on the conduction mechanism, the reduction of the humidity cross-sensitivities and also on the various reaction mechanisms. Then, the technology for constructing gas sensors of this kind will be described. Examples that have already been implemented, for example, λ detection, O2 measurements in the exhaust gases from incinerators, methane alarms, and air quality control, as well as certain trends in development, are discussed.
