The surface nature and the surface-treatment of silicon-, aluminium-, titanium nitride and zirconium-, titanium boride exposed to an atmosphere were investigated from their X-ray photoelectron spectra and the pyrolyses of nitrides and borides treated with alcohols and organosilylchlorides. It was found that the surface molecules of these nitrides and borides reacted with oxygen and water in an atmosphere and formed the oxide layers. These then reacted further with water in an atmosphere. Thereafter the surface of these nitrides and bromides was composed of these surface hydroxides thus formed. The surface-treatment of these nitrides and borides was found to be applicable to treat similar to that of the corresponding oxide powders.
