“…After the melt was held for 3 hrs in air at 80(tC, and permitted to crystallize, 0.02% Pt was found to be present in the V 2 0 S crystals. Pantony and Vasu [176] started with (Johnson and Matthey) "High Purity" Vps (99.99%), and an oxygen atmosphere to minimize dissociation of the melts. The sodium metavanadate-Vps melts [1761 were similarly prepared in Pt crucibles under oxygen.…”

“…[179,175]. Pantony attributes this to the high purity of the V 2 0, used in their study, to the absence of contamination by silica, alumina or zirconia, and to the use of an ambient oxygen atmosphere to repress dissociation: The density data for molten V 2 0, in an ambient oxygen atmosphere are presented graphically in [176]: the densities vary non-linearly with temperature.…”

Evaluated data for the four properties, density, surface tension, viscosity, and electrical conductance are reported for salt systems in which both the anionic and cationic species may differ. This contrasts with the systems in the preceding publications in this series in which the anionic species were, in general, the same in the binary mixtures. The results are reported in equation form, with brief tables of numerical· values. A cross index by salt system was compiled and is included for ease of accessing the data tables.

“…The old paper by Milan (6) gave, at 1130 K, results one order of magnitude higher than the present work. The results of Allen, Kubaschewski, and Goldbeck (7) On the other hand, it must be stated that nitrogen has not been found to be inert in the presence of melts containing V205 (15), and that its use (13) to establish oxygen partial pressures in this system, may in part account for the discrepancy.…”

The equilibrium oxygen pressure in the V20-V20, system from temperatures near melting, up to 1130 K has been measured. A closed system solid electrolyte cell with a Ni/NiO reference electrode was used. The results of the present investigation for liquid solutions consistently extend those reported for solid solutions. Chem. 54, 1967Chem. 54, (1976. On a mesure la tension d'equilibre de I'oxygtne dans le systeme V205-V,O, a partir de temperatures proches de la fusion et jusqu'a 1130 K.

Les resultats presentes ici pour les solutions liquides constituent une extension des donnees experimentales communiquees par d'autres chercheurs pour les solutions solides.

zum 70. Geburtstag am 21. 9.1972 gewidmet. Nach Pantony und Vasu hangen die korrosiven Eigenschaften einer Vanadinpentoxidschmelze von ihrer Fahigkeit zur Sauerstoffiibertragung ab (4). Sie fanden, dai3 die Konzentration des in der Schmelze beweglichen Sauerstofis teilweise durch das Gleichgewicht beschrieben werden kann. Dieses Gleichgewicht wird durch andere Stoffe beeinflufit. Seit langem bekannt und haufig untersucht worden sind zum Beispiel die Eigenschaften einer Schmelzmischung aus Na2SO4 und V205 (1-6). Wird zu Vanadinpentoxid Natriumsulfat im Molverhaltnis V,0JNaeS04 = 611 gegeben und diese Mischung geschmolzen, so entsteht die Verbindung N a e O . 6V205: Na,SO, + 6V,O, * Na,O . 6V,O, + SO, + 1 / 2 0 g . Beim Erstarren dieses Vanadates wird Sauerstofi abgegeben, der beim Schmelzen des Vanadylvanadates wieder aufgenommen wird: N a 2 0 . 6V205 p
