  • Product produced by coating a substrate with an electrically conductive layer
    Patent number: 5851642
    Abstract: 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.
    Type: Grant
    Filed: July 10, 1989
    Date of Patent: December 22, 1998
    Assignee: Saint-Gobain Vitrage
    Inventors: Vincent Sauvinet, Jean Bletry, Micheline Bonnaud, Maurice Trouve
