Sensor for detecting the stoichiometric composition in a combustion flame
The performance of Sr0.65La0.35Co0.7Fe0.3O3−δ as a sensor, as well as it calatytic activity, are studied in relation to additions of SrTiO3 and the further addition of Pd.
The temperature dependence of the sensor with more than 40 mol% SrTiO3 at temperature below 400°C is semiconductor like and does not rely on the gas atmosphere, which allows us to use the material as a temperature sensor (e.g)., a flame detector). Gas sensitivity occurs at temperature above 400°C and the addition of 60 to 70 mol% SrTiO3 gives the highest sensitivity, response and catalytic activity. The working temperature can be lowered by about 100°C by the further addition of Pd. Additions of SrTiO3 and Pd also improve the lifetime of the device.
