Abstract
Abstract Transparent, haze-free tin oxide coatings on glass are obtained by chemical vapor deposition of liquid monophenyltin trichloride. The method includes the steps of vaporizing liquid monophenyltin trichloride and contacting the vapor in an oxidizing atmosphere with a substrate at an elevated substrate temperature, preferably about 450° to 600° C. The tin oxide coating on glass produced by this method has a haze which is less than 1%, and is substantially equal to the haze value for uncoated glass.
