METHOD FOR MANUFACTURING POROUS NIOBIUM MATERIAL, POROUS NIOBIUM MATERIAL, AND ELECTROLYTIC CAPACITOR AND CATALYST SUPPORT PROVIDED WITH THE SAME |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a capacitor which has increased withstanding voltage, has a reduced leakage current, and does not cause a change of capacitance. <P>SOLUTION: A method for manufacturing a porous niobium material having a porous oxide film on the surface of a substrate made from niobium includes anodizing the surface of the substrate in an electrolytic solution containing hydrofluoric acid. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
