ABSTRACT OF THE DISCLOSURE Electrically-conductive films of tin oxide are prepared by a novel process utilizing gaseous chemical compounds which react to form a tin-fluorine bond at a temperature which is (1) high enough so that the newly-created tin-fluorine bond-bearing mole- cule remains in the vapor phase; and (2) low enough so that oxida- tion of the molecule occurs only after the indicated re-arrangement. Films prepared by the process of the invention are characterized by surface resistances as low as 1 ohm per square when the film thickness is as thin as about a micron. These films are also characterized by extremely good reflectance of infrared radiation.
