Abstract in another language
The metal oxide strontium titanate is a promising material for resistive high temperature oxygen sensors (T > 1000 K), that can be applied to control combustion engines. However, a disadvantage of this and of many other metal oxides is the strong temperature dependence of conductivity. In this work, we show that the temperature dependence of Sr(Ti1-xFex)O3-δ can be adjusted by the iron content. For x = 0.35 the thermal activation of the conductivity is near zero for a distinct temperature and oxygen partial pressure range (T = 1000 K - 1200 K, pO2 = 10 to 10^5 Pa). Short response times in the range of 10 ms can be realized by using sensors in thick film technology.
