Description
BaSnO3 with cubic perovskite structure exhibits good dielectric properties. Because of these characteristic properties, BaSnO3 ceramic is becoming more and more important in material technology. It can be used to prepare thermally stable capacitors and to fabricate ceramic boundary layer capacitors.
In recent years, BaSnO3 has been found to be a very promising sensor material and has therefore received the most attention. In pure as well as doped forms, stannates have been investigated as potential solid-state sensor materials for many gases, including CO, NOx, H2 and CO2. BaSnO3 has also been used in the preparation of multifunctional temperature–humidity–gas sensors by combining it with BaTiO3. Detection of gas in BaSnO3 sensors is achieved by measurement of the electrical properties changes such as resistance and conductivity. The changes are induced in the semiconducting oxide form of BaSnO3 following adsorption of any given gases on the solid surface. The gas sensitivity of this semiconducting oxide is related to the surface reaction process.
