HEAT-REFLECTING GLASS AND METHOD FOR MANUFACTURING THE SAME

摘要

On the surface of a glass substrate is formed by hydrolysis or thermal decomposition a light-transmissive film of a metallic oxide having a refractive index higher than that of glass and colloidal particles of metallic palladium or of metallic palladium and metallic gold, said particles being uniformly dispersed in said metallic oxide. The film has the transmission color of bluish gray, neutral gray or yellowish gray and is capable of reflecting about 30 to 40 percent of solar energy radiation. The film also has superior mechanical strength and chemical stability, so that glass having such a film can be successfully used as a heat-reflecting glass in single-pane installations.
