The oxygen permeability of dense La Sr CoO membranes has been measured in the range 750-11008C under 0.3 0.7 32d various oxygen partial pressure gradients. A sweep gas method was employed. Results indicate that in the range of thickness 0.057-0.215 cm used in the present study, the oxygen flux is pr
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 700-900Β°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
