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 coefficient (D *) 56t4 kJ mol’ The absolute values for both k and D * are among the highest known in the literature. The characteristic thickness at a po, of 2.1 X lo4 Pa is calculated to lie in the range 0.70… CONTINUE READING
