CaO film

Even when native CaO films cover the Ca, they may be replaced by CaCl2 surface species according to the following equation ...

Ca transport is faster than O in CaO film. ° Concentration of Ca+ is much higher than LC because Li+ is thermodynamically unstable when Ca metal is present. 

Ca+ ion is much smaller than Li atom. Some possibility of isolated Li incorporation probably as atomic form in grain boundaries, triple points, or defected zone in CaO film.

HARRIOTT 25 suggested that, as a result of the effects of interfaeial tension, the layers of fluid in the immediate vicinity of the interface would frequently be unaffected by the mixing process postulated in the penetration theory. There would then be a thin laminar layer unaffected by the mixing process and offering a constant resistance to mass transfer. The overall resistance may be calculated in a manner similar to that used in the previous section where the total resistance to transfer was made up of two components—a Him resistance in one phase and a penetration model resistance in the other. It is necessary in equation 10.132 to put the Henry s law constant equal to unity and the diffusivity Df in the film equal to that in the remainder of the fluid D. The driving force is then CAi — CAo in place of C Ao — JPCAo, and the mass transfer rate at time t is given for a film thickness L by ... 

Silver films and Ag-CaO-SragOg cermets were chosen as the anodic electrocatalysts because of their high electrical conductivity, which is necessary for electrocatalytic operation, and also because of their high (>95%) selectivity to Cg hydrocarbons at very low (<2%) CH conversions [9].
