FIELD: electricity.
SUBSTANCE: invention relates to production of electric capacitors. Method of producing tantalum capacitor anodes involves mixing anhydrous tantalum powder and binder, pressing anodes of condensers into workpieces, subliming the binder, treating the workpieces with a solution of a surfactant, washing the workpieces with desalted water, vacuum drying and vacuum sintering of tantalum anodes. Binder used is camphor or stearic acid solution in ethyl alcohol. Surfactant used is an aqueous solution of sulphanol and / or synthanol. After molding and sublimation, anode workpieces are treated with surfactant solution, followed by washing with desalted water at high temperature and stirring. Drying of blanks is carried out in vacuum at temperature 150-160°C, residual pressure of not more than 0.15 Pa and duration of not less than 20 minutes.
EFFECT: obtaining anodes without defects with reduction of residual content of carbon.
