摘 要：<正> Many ionocovalent oxide materials are either semiconducting or insulating in nature.One of the most im-portant quantities characterising these materials,therefore,is the bandgap energy.The thermodynamic ap-proaches to the bandgaps of oxides are briefly described and some interracial phenomena with oxides are pres-ented.The standard electrode potentials of oxide electrodes and the heterogeneous catalytic behaviours of theoxides as well as the wetting and adhesion in liquid metal/oxide systems can be closely related to the bandgapenergies of the oxides.The interfacial phenomena involving the ionocovalent oxides are associated with theelectronic processes.
