A niobium suboxide powder comprising niobium suboxide particles having a bulk nitrogen content of between 500 to 20,000 ppm. The nitrogen is distributed in the bulk of the powder particles. The nitrogen at least partly is present in the form of at least one of Nb2N crystals or niobium oxynitride crystals.
