The self-consistent unrestricted Hartree-Fock method was used to study the adsorption of argon on cluster models of Al₂O₃ surfaces. We have considered surfaces parallel and perpendicular to the hexagonal c axis and obtained a maximum binding of 0.5 eV, in good agreement with experiment. We propose a simple electrostatic model to account for this binding.
