Abstract in another language

Sulfur dioxide strongly affects temperature independent resistive oxygen sensors of SrTi1-xFexO3-δ.Time dependent sensor deterioration was investigated for lanthanum doped SrTi0.65Fe0.35O3-δ(STF35). Parameters were sulfur dioxide concentration, oxygen partial pressure, temperature, and sensor morphology. The sensor poisoning consists of two steps. At lower temperatures sulfur dioxide adsorption and sulfate ion formation at the grain surface is suggested. At higher temperatures the material decomposes into SrSO4,iron depleted STF35, and Fe2TiO5.
