NIOBIUM SUBOXIDE POWDER, NIOBIUM SUBOXIDE ANODE AND SOLID-ELECTROLYTE CAPACITOR Russian patent published in 2009 - IPC C01G33/00 H01G9/42 H01G9/15

Abstract RU 2369563 C2

FIELD: chemistry.

SUBSTANCE: niobium suboxide powder contains 100-600 million parts magnesium and/or 50-400 million parts molybdenum and/or tungsten. Niobium suboxide anode consists of agglomerated primary particles with diametre 0.3-1.5 mcm. Solid-electrolyte capacitor contains such an anode.

EFFECT: invention allows for reducing variation of stray current when making one batch of capacitors and obtaining niobium pentoxide powder, suitable for making capacitors.
