Tantalpulver,
wobei, wenn das Tantalpulver zu einer Anode eines Elektrolytkondensators
geformt wird, die Anode eine Kapazitat von 450.000 bis 800.000 μFV/g
aufweist, gemessen durch das Pressen des Tantalpulvers zu Pellets
mit Tantalzuleitungsdrahten, mit einer Pressdichte von
4,5 g/cm 3 , Sintern der Pellets, Anodisieren
der gesinterten Pellets in einer wassrigen Phosphorsaurelosung
mit einer Konzentration von 0,1 Vol.-% unter einer Spannung von
6 V und einem Strom von 90 mA/g, um anodisierte Pellets zu bilden
und Prufen der Kapazitat in einer wassrigen
Schwefelsaurelosung mit einer Konzentration von
30,5 Vol.-% bei einer Temperatur von 25°C unter einer Frequenz
von 120 Hz und einer Spannung von 1,5 V.read more

Methods to partially reduce a niobium metal oxide and oxygen reduced niobium oxides
TL;DR: In this article, the process of 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 niibium oxide to the getter materials, and for a sufficient time and at a sufficient temperature to form an oxygen reduced Niobium oxides and/or suboxides is described.
