What is Formation and transformation of δ-Nb2O5 solid solutions in the system Nb2O5Al2O3 about?
I n the system Nb,O,-Al,O,, solid solutions of metastable S-Nb20, (hexagonal) are formed up to 50 molyo A1,0, from amorphous materials prepared by the simultaneous hydrolysis of niobium and aluminium alkoxides. The values of the lattice parameter a are relatively constant regardleas of composition, while parameter c decreases linearly with increasing Al,O, content. The 6to y-Nb,O, (orthorhombic) transformation occurs a t w 640°C to w 700°C. The solid solution containing 50 molyo Al,O, transforms t o monoclinic NbAIO, at 800" to 860°C. ## Bildung und Umwandlung von festen Liisungen des 6-Nb206 im Nb206 --Al~O~-System Inhaltsiibersicht. I m System Nb,O,-Al,O, werden (bis 50 Mol-% A1,0,) mit metastabilem, hexagonalem 6-Nb20, feste Losungen gebildet, bei der Praparation aus den amorphen Substanzen, die durch simultane Hydrolyse von Niob-und Aluminiurnalkoxid erhalten werden. Die Werte des Gitterparameters a sind unabhiingig von der Zusammensetzung, wihrend der Parameter c linear abnimmt mit steigendem Al,O,-Gehalt. Der tfbergang 8-+y-Nb20, (orthorhombisch) erfolgt bei 640°C bis 700°C. Die 50 Mol-% Al,O,-enthaltende feste Losung geht bei 800" bis 860°C in monoklines NbAIO, iiber.
