Title: SYNTHESIS OF RUBY FILMS BY ANODIC OXIDATION OF ALUMINUM
Abstract: Abstract An alpha alumina film incorporated with chromium oxide was prepared on aluminum by two-step anodic oxidation. Aluminum was anodized in sulfuric acid and adsorbed chromate ions into the pores of the film. A chromate ions adsorbed alumina film was reanodized in bisulfate melt. The film thus prepared has optical properties similar to a ruby synthesized by the Verneuil method.
