Abstract

A dipping process for the production of cadmium stannate layers on a substrate, preferably glass, which comprises: PA1 (a) dipping said substrate into an alcoholic solution of a reaction product containing cadmium and tin, said solution consisting essentially of compounds having hydrolyzable and pyrolyzable residues; PA1 (b) withdrawing the substrate from said solution in a humid atmosphere; and PA1 (c) gradually heating the coated substrate to 650.degree. C., whereby hydrolysis and pyrolysis removes said residues from the coated substrate to form a coated substrate in which the molar ratio Cd:Sn corresponds to that of said alcoholic dipping solution.
