The surface oxygen exchange of Lao.3Sro,,Co0,\_6 has been studied by 'SO/'hO exchange followed by dynamic SIMS analysis in the temperature region 700-900°C at a po, of 2.1 X lo4 Pa. The activation energy for the surface exchange rate (k) is 283 kJ mol -' and for the oxygen tracer diffusion coefficie
