ABSTRACT:
An electrolytic solution comprising glycerine and an organic salt, an inorganic salt, or mixtures thereof, and having a pH of less than about 7. The electrolytic solution has a water content of less than 0.1 weight percent and is prepared by mixing the glycerine and the salt or their acidic and basic ionogen components and heating to above 150.degree. C. A method of anodizing a metal comprising forming a film on the metal with said electrolytic solution. The metal is preferably a valve metal, such as tantalum, and the film is formed at a temperature of 150.degree. C. or higher.
