| Abstract: |
| Sintered tantalum nitride anodes were prepared with tantalum nitride nanopowders. The sintered anode slugs were examined by XRD. The effects of formation solution in terms of its variety, concentration and temperature, current density and formation voltage on electrical characteristics were studied. The results show that the anode slugs are made of pure tantalum nitride phase, and the optimum anodizing process conditions including H3PO4 concentration of 0.01%, temperature of formation solutions of 55 ℃, current density of 40 mA/g and the formation voltage of less than 16 V. |
