In this paper we present results of structural analysis of SnO2films deposited by spray pyrolysis and designed for application in conductometric gas sensors. The aim of this analysis was summarizing the results obtained in this field, highlighting a correlation between material structure and its gas sensing properties, and formulating some general regularities typical for metal oxides.
