“…Vacuum Fusion. The advantages of using a platinum bath as the reaction medium in the vacuum fusion determinations of oxygen have been enumerated (8, 4, 7, 16, 28). The data obtained in the present investigation indicate that these advantages apply to the vanadium system as well.…”

“…The classical vacuum fusion {29) and the more recently developed inert-gas fusion {21, 28) techniques have found widest application to the determination of oxygen in metals. Both techniques involve high temperature fusion of the metal specimen in a graphite crucible, under environmental conditions such that the carbon reduction reaction [M + MzOy] + C -> MC + + yCO (1) leads to the quantitative evolution of carbon monoxide.…”

On leaching the melt, most constituents are rendered insoluble either as hydroxides or calcium salts, except for rhenium and a small amount of molybdenum. A rather complete separation of the elements is obtained, as shown by the fact that no precipitate is formed in the filtrate from rocks on adjusting the pH to 7.5 with ammonium hydroxide. About 680 and 440 Mg. of Mo03, respectively, were found in the filtrate when 0.5 and 0.3 gram of MoS2 were tested; 50 Mg. and less than 5 Mg• of Mo03 were found when 0.5 gram of W-l was taken to which 1 mg. and 100 Mg• of Mo03, respectively, had been added. Table V. Test of Procedure on Mixtures of W-l and Molybdenite Containing 70 p.p.m. of Re Mix taken, gram Re in mix,__Re recovered, µg. MoS2 W-l Mg.

“…For most steels the platinum bath was found not to be necessary and a dry bath technique very similar to that proposed by Walter was adequate. For certain alloys, the platinum bath provided a more satisfactory method and has been used in both vacuum fusion equipment and in the inert gas technique (173).…”

“…Precise knowledge of the total oxygen content is, therefore, required to evaluate properly the effect of oxygen on the physical properties of the metal and to provide analytical control for commercial metal. Various modifications of the vacuum fusion (9,12, IS, 17) and inert gas fusion (10,14) techniques and vacuum extraction (8) have been employed to obtain this analytical information. As part of a continuing study on the scope of application of the emission spectrometric techniques developed in our laboratories (2)(3)(4)(5)(6)(7), experimental conditions were established for the determination of oxygen in niobium metal.…”
