Abstract

Doped and undoped films made from SrTiO3 have proved to be promising for use in high-temperature oxygen sensors (6002 have only a reducing effect when present in concentration of 1% in oxygen-containing gas mixtures (1% O2, the remainder being N2).The strongest effect is seen at about 575 °C, H2, H2O and Ch4 also have a reducing effect in oxygen-containing atmospheres below a temperature that is dependent on the reactive gas in question. However, above these temperatures such gases have an 'oxidizing' effect. These effects can be explained on the basis of a surface model for SrTiO3 that assumes that the positive surface charge at the grain surface is at least partially counterbalanced by OH groups.
