FIELD: electrical engineering. SUBSTANCE: method involves production of powder by means of interaction of alkali elements of Group V - B amounting to 500-7000 parts with respect to one million nitrogen parts and 700-3000 parts amounting to one million oxygen parts. Electric losses are decreased by, at least, 28% for electrodes that are anodized at voltage of 100 V and more, with respect to electrodes and complete capacitors that are produced from non-doped materials. For baking temperature of 1400-1800 C, specific charge reaches level up to 25000 mcFV/g. EFFECT: decreased electric losses. 31 cl, 4 dwg, 3 tbl, 12 ex
