Zusammenfassung

Es wurde die Zusammensetzung von Lanthanwolframat-Niederschlägen untersucht, die sich aus Lanthannitrat- und Natriumwolframat-Lösungen verschiedener Polymerisationsgrade bilden. Die Reaktionen wurden bei verschiedenem pH, in rein wässrigem oder wässrig-alkoholischem Milieu durch amperometrische Titration verfolgt. Im pH-Bereich von 5,5–6,5 bildet sich La2O3 · 3WO3, bei einem pH von 4,2–5,5 La2O3 · 7WO3.
