Variation of the porous structure and leakage currents of anodes of niobium condensers in electrolytic oxidation

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

Shaping of the anodes results in a large reduction of the total volume and dimensions of the pores. The magnitude of this reduction is determined unambiguously by the dispersion of the initial powder and oxidation voltage. Shaping results in the formation of a certain number of closed pores.

Formation of closed porosity is accompanied by a large reduction of the leakage currents. This is explained by a reduction of the number of impurity atoms concentrated mainly on the surface of sintered anodes. Therefore, the high-dispersion powders which contain, per unit mass, approximately the same amount of impurities as the standard powders can be used to produce anodes with permissible leakage currents at low sintering temperatures.
