Al2O3- BSST Based Chemical Sensors for Ammonia Gas Sensing
Gas sensing behaviour of pure and modified (Ba0.9Sr0.1)(Sn0.5Ti0.5)O3 (BSST) thick films is reported in this article. The surface of the BSST thick film was modified by dipping it into aqueous solution of AlCl3, for different intervals of time. These films were then dried at 500 0C for 24 hours in a...

Gas sensing behaviour of pure and modified (Ba0.9Sr0.1)(Sn0.5Ti0.5)O3 (BSST) thick films is reported in this article. The surface of the BSST thick film was modified by dipping it into aqueous solution of AlCl3, for different intervals of time. These films were then dried at 500 0C for 24 hours in air ambient for transformation of AlCl3 into Al2O3, for the evaporation of organic binders and also to improve the texture of the film. The gas response, selectivity, response and recovery time of the sensors were measured and presented. The role played by the aluminium species to improve the gas sensing performance of the sensors is discussed.
