MIXTURE OF POWDERS, CONTAINING NIOBIUM SUBOXIDE AND METAL FOR ELECTRONIC TUBES, PRODUCTION OF MOULDED BODY FROM SAID MIXTURE FOR MAKING ANODES FOR SOLID-ELECTROLYTE CAPACITORS, METHOD OF MAKING CAPACITOR ANODE BASED ON NIOBIUM SUBOXIDE, SOLID-ELECTROLYTE CAPACITOR AND ANODE FOR SAID CAPACITOR Russian patent published in 2009 - IPC H01G9/52 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, particularly to making capacitors based on niobium suboxide NbO_x powder, where 0.7 < x < 1.3, which, before moulding, is mixed with powder of a valve metal - niobium. A powder is also proposed for making an anode for a solid-electrolyte capacitor, consisting of tertiary agglomerated particles, which are agglomerates from primary and/or secondary particles of niobium suboxide and primary and/or secondary particles of niobium metal, which after pressed into a work piece to density of 2.8 g/cm³ has compression strength of over 2 kg. The anode for a solid-electrolyte capacitor has a spongy sintered structure with breaking strength of the wire of the anode material of over 2 kg.

EFFECT: improved flow rate of powder when making anodes for capacitors based on niobium suboxide, with high compression strength at relatively low sintering temperature.
