Very high volt oxide formation of aluminum for electrolytic capacitors |
摘要 |
An anode foil treatment method produces a useful high quality oxide with inherently high capacitance at voltages as high as 750 Volts or more. The anode foil treatment method comprises a series of formation and relaxation steps. Oxide layer formation is performed in a forming mixture that includes a high molecular weight dicarboxylic acid that is made into a salt and a strong base. The concentration of the dicarboxylic acid is carefully monitored and kept within a narrow band. The complex by-product of the dicarboxylic salt created during formation process is kept below a fixed maximum level.
