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 from 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 by fabricating a pellet of niobium oxide and heat treating the pellet in an atmosphere which permits the transfer of oxygen to a getter material, and for a sufficient time and temperature to form an electrode body, and anodizing the electrode body.
