Description

Preliminary data are presented for a series of glasses using some of the special features of neutron diffraction. In vitreous K2O x TiO2 x 2SiO2 each Ti atom is on average surrounded by 5.2 oxygen atoms at a distance of 1.95 A, whereas the structure of V2O5 x TeO2 is dominated by distorted TeO6 octahedra. Features in the magnetic correlation function for vitreous O x 79Fe2O3 x P2O5 occur at the Fe,Fe distance found in crystalline FePO4. (orig.)

Abstract (German)

Es wurden vorlaeufige Daten ueber eine Reihe von Glasen vorgelegt, die mit Hilfe spezieller Neutronendiffraktionsmethoden ermittelt wurden. In glasfoermigem K2O x TiO2 x 2SiO2 ist jedes Ti-Atom in einer mittleren Entfernung von 1.95 A von durchschnittlich 5,2 Sauerstoffatomen umgeben, waehrend in der Struktur von V2O5-TeO2 verzerrte TeO6-Oktaeder dominieren. Besondere Merkmale in der magnetischen Korrelationsfunktion von glasfoermigem O x 79FeO2O3 x P2O5 finden sich bei den in kristallinem FePO4 gefundenen Fe-Fe-Entfernungen. (orig.)
