Method for coating a substrate with an electrically conductive layer

摘要

A method for coating a substrate, preferably of glass, with a pyrolyzed transparent, electroconductive layer. The coating is comprised of indium formate, optionally mixed with a powdered or gaseous tin compound or a gaseous organotin compound. The coating layer is deposited upon a hot substrate whereupon it pyrolytically decomposes, forming a layer which is subsequently heat treated in a reducing or an oxidizing atmosphere to optionally enhance the low emissivity and low resistivity of the coating or reduce said low emissivity and low resistivity properties.
