NIOBIUM SUBOXIDE Russian patent published in 2011 - IPC C01G33/00

Abstract RU 2424982 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in production of solid-electrolyte capacitors. Powdered niobium metal used as a precursor is azotised before conversion into powdered niobium suboxide of formula NbO_x, in which 0.7 < x < 1.3, having nitrogen content between 500 and 20000 parts per million, which is semiuniformly distributed in volume of the powder particles.

EFFECT: obtaining niobium suboxide which provides high working temperature of capacitors made from said suboxide, having high breakdown voltage.
