X-ray phase and elemental composition analysis of anodic alumina growth in sodium hydroxide solutions
With the help of X-ray diffraction and elemental analysis, the composition and structure of anodic alumina film produced by anode process in sodium hydroxide based electrolyte have been investigated. The structure of the crystalline phases constituent of alumina was determined. A high degree of hydration of anodic alumina formed in sodium hydroxide based electrolyte is ascertained.
