Barium stannate, BaSnO3, is a cubic perovskite like compound that behaves as a pure n-type semiconductor Thus, high performance applications, such as sensitive material for exhaust gas sensors, are some of the main reasons for the BaSnO3 demand. Other particular features of this perovskite, and hence the interest in it, are principally related to the easy modification of its electrical properties and its high temperature stability, where the responses of gas-sensitive metal oxides are fast and independent on fluctuations in humidity. In the last years, experimental studies have been carried out, in order to determine its potential usefulness in gas sensors production as tools for detecting toxic and inflammable gases such as CO.
