Patent number: 6268019Abstract: The present invention concerns the deposition of fluorine modified, titanium dioxide films (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition (APCVD) using TiCl4 vapor. The invention is also suitable for depositing other metallic oxide films from their metallic halides such as SnCl4, GeCl4, and VCl4. The present invention provides a process that deposits a novel, fluorine modified, titanium dioxide film (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition using TiCl4 vapor. The process uses injection of TiCl4 into a hot, nonoxygen containing carrier gas and blends the carrier gas and TiCl4 vapor with an oxygen containing gas stream containing a haze reducing quantity of a fluorine containing compound before contacting a surface of hot glass with the blended mixture. The process is capable of depositing a fluorine modified, TiO2 film at deposition rates exceeding 900 Å per second. The crystalline phase of the fluorine modified film is essentially anatase.Type: GrantFiled: May 19, 1999Date of Patent: July 31, 2001Assignee: ATOFINA Chemicals, Inc.Inventor: Glenn P. Florczak
