The formation of anodic oxide films on tantalum in non-aqueous solutions

摘要: Abstract The anodic films formed on tantalum in many non-aqueous solutions have been found to consist of two layers. Next the metal there is a layer Ta 2 O 5 with same characteristics as that aqueous electrolytes, while between film and solution which characteristic forming solution. Changes relative thicknesses layers formation rate, temperature, result dependence rate history film. During oxidation it has ions move out through react oxygen at oxide-electrolyte interface.
