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 NbOx, 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. ^ 14 cl, 13 dwg, 1 tbl, 6 ex |
