Abstract
Oxygen sensitive resistance materials for use with oxygen sensors, in particular .lambda. probes are described. These materials are based on the fact that with complex metal oxides it is possible--by adding suitable doping substances--to achieve a negligible temperature dependence of the electric resistance of these materials for different oxygen partial pressures and to preset it to a desired partial pressure value.
