Abstract

The conditions of preparation of nanoporous Nb anodes of electrolytic condensers from fine-dispersed Nb powders were studied and optimized. Mechanisms of behavior of the powders under pressing and vacuum baking as well as dependencies of main electric properties of condensers on dispersity of initial powders and on conditions of anode preparation on a base of the powders were determined. The anodes having specific surface up to 1 m2/g and average pore radius of 300—500 nm were prepared. It was shown that specific electric charge of such condensers in 5—8 times exceeded standard values and was equal to 5500 ?Ñ/cm3 , but the values of leakage current and tangent of dielectric loss angle were on standard level.
