Selective oxidations that take place at the surface of dental gold alloys were studies in terms of RHEED. The surfaces of the alloy containing 0.4 weight percent Sn was covered with a chemically active SnO2 layer when oxidized at 1000°C in air. This oxide layer served for mating the alloy substrate with the dental porcelain blending with SnO2. The surface of the alloy containing 0.1 percent Si was covered wih a SiO2 layer when calcined at 1000°C in air. This mineralized surface could coment together with the conventional dental porcelain.
