Vanadium/Oxygen System in the Analysis of Sodium for Oxygen

摘要

An investigation of the V-O-Na system at 1023 K is described for oxygen in sodium contents of 5 to 25 ppM. Electron spectroscopy combined with depth profiling is used to determine the vanadium/oxygen ratios inwards from the surface of vanadium foil and these ratios are compared with theoretical predictions. The validity of the vanadium wire technique as an analytical method is examined and a model for the vanadium oxidation is suggested. (Atomindex citation 13:660991)
