FIELD: production of niobium oxide-semiconductor capacitors such as enhanced-voltage ones.
SUBSTANCE: proposed method for manufacturing porous niobium bulk anode involves compression of anode pellets from hydration treated niobium powder, sintering of niobium anode pellets, molding of sintered anodes, and additional molding of anodes in hot electrolyte; anodes are to be molded in two stages; first stage lasting 1 h involves use of phosphoric acid aqueous solution at normal room temperature and second stage lasting 4 h , use of phosphoric acid aqueous solution mixed up with deionized water and ethylene glycol at room temperature of 8 °C.
EFFECT: enhanced operating voltage of niobium anodes produced in this way.
