The solid solubility of oxygen in palladium in equilibrium with gaseous oxygen was deduced from absorption-desorption experiments at 1123 to 1173K and oxygen partial pressures between 2.7 x 103 and 4.0 x 104Pa. The temperature dependence of diffusivity obeyed:

D(m2/s) = 2.33 x 10-7exp[-102.76(kJ/mol)/RT]
