Abstract

Porous anode bodies suitable for use in solid state capacitors, the porous anode bodies prepared by processes which include providing a niobium suboxide powder comprising niobium suboxide particles having a bulk nitrogen content of 500 to 20,000 ppm, and agglomerating and coalescing the powder; and capacitors incorporating such anode bodies.
