Reactions of Molten Titanium with Certain Refractory Oxides

Abstract

of negative ions in hydrocarbons. It might be of interest to find a reversible electrode for the positive ions; it would form the counterpart to the aliphatic electrode described. ABSTRACT Titanium metal was melted in vacuo in contact with A1203, BeO, and ThO2 respectively. The metal reacted vigorously with A1203, less so with BeO, and slightly with ThO~. Qualitatively, the relative positions of the oxides on the scale of reactivity with titanium are consistent with the oxygen dissociation pressures as calculated from thermochemical data.It was concluded that of the three oxides studied only thorium oxide showed any promise as a crucible material for melting titanium or titaniumbase alloys.

Formation and Degradation of Oxide Films on Beryllium

“…Оксиды могут вступать во взаимодействие с окружающей атмосферой, в частности, с восстанови-тельными средами и со средами, содержащими углерод [35][36][37][38][39][40][41][42][43][44][45]. Обычно тугоплавкие оксиды устойчи-вы к воздействию различных газовых сред.…”

Fiftieth Anniversary: Rare Metals and The Electrochemical Society

“…The Columbus symposium, especially, was of value because there were so many papers on the production of the rare metals themselves. A number were also presented at the fall meeting in New York (92)(93)(94)(95)(96)(97).…”
