Abstract
A method is disclosed for pyrolytically forming electroconductive tin oxide films having higher resistivity for a given thickness than tin oxide films formed by known methods by adding to the film forming solution an organic compound which retards the rate of film formation reducing the particle size of the tin oxide film thus increasing the resistivity of the film. Small quantities of an organic compound such as cresol or benzyl alcohol added to the film-forming solution may increase the resistivity by a factor of five for a typical film thickness.
