Abstract

A process for the production of transparent, electrically conductive, infrared-reflecting indium oxide-tin oxide layers, especially on glass panes, involves steps wherein the glass panes are dipped into a first solution containing a hydrolyzable silicon compound and hydrolyzable compounds of titanium, zirconium, aluminum, tin or tantalum; PA1 the glass panes are heated up to 450.degree. C. in a moisture-containing atmosphere; PA1 the initially coated panes are dipped into a second solution containing hydrolyzable compounds of indium and of tin; PA1 the panes are dried at temperatures below 250.degree. C.; and PA1 the panes are finally heated up to 550.degree. C. in a reducing atmosphere.
