Röntgenspektrometrische Bestimmung von Tantal und Niob und einiger Begleitelemente in tantalniobhaltigen Stoffen

Abstract: Analyse tantalniobhaltiger Stoffe unter Verwendung von Lösungen. Bestimmung von Tantal und Niob in Erzen, Schlacken und Legierungen nach chemischer Isolierung der Erdsäuren. Bestimmung von Tantal und Niob und einigen Begleitelementen in säurelöslichen Legierungen ohne chemische Vortrennung. Bestimmung von Tantal und Niob mit gleichzeitiger Ermittlung des Eisen‐, Mangan‐ und Zinngehaltes in Erzen durch Boraxaufschluß. Herstellung der Standardproben. Angabe von Arbeitsvorschriften. Mitteilung von Beleganalysen.

“…Utilization of 2.5% and 5.0% hydrofluoric acid for dissolving the KzS207 cake wras unsuitable in that tantalum was not retained in solution. However, Bruch (S) and Rothmann et al (10) have used a combination of hydrofluoric and other acids and achieved favorable analyses of various elements including tantalum and niobium in ferro alloys and ores.…”
