Methods to at least partially reduce a niobium oxide are described wherein the process includes heat treating the niobium oxide in the presence of a getter material and in an atmosphere which permits the transfer of oxygen atoms form the niobium oxide to the getter material, and for a sufficient time and at a sufficient temperature to form an oxygen reduced niobium oxide. Niobium oxides and/or suboxides are also described as well as capacitors containing anodes made from the niobium oxides and suboxides.
L'invention concerne des procédés permettant de réduire partiellement un oxyde de niobium, consistant à soumettre l'oxyde de niobium à un traitement thermique en présence d'un matériau de type getter et dans une atmosphère permettant le transfert d'atomes d'oxygène de l'oxyde de niobium au matériau de type getter, pendant une durée suffisante et à une température suffisante pour former un oxyde de niobium à teneur réduite en oxygène. L'invention concerne également des oxydes et/ou sous-oxydes de niobium, ainsi que des condensateurs contenant des anodes produites à partir de ces oxydes et sous-oxydes de niobium.
