A developed strict kinetic model for the growth of porous anodic Al2O3 films was employed to the experimental results obtained at different bath temperatures and current densities of Al anodization. Treatment of the values of parameters involved in the kinetic equation showed that the pore/cell surface density depends only on current density, the pore base diameter depends only on bath temperature, and the equations In n = p ln J + p'' and ln D-b = g ln T + g accurately apply. By using these equations, mathematical models for other structural features were also formulated describing their dependence on the anodization conditions.
