摘要

The outgassing of nitrogen and oxygen from vanadium is discussed, taking the literature into consideration. The amount of dissolved oxygen can be decreased by melting in a high vacuum, whereas the dissolved nitrogen approaches a limiting value of 0.3% by weight. For lower initial concentrations of nitrogen the concentration of nitrogen in the molten mass increases; at higher initial nitrogen concentrations partial outgassing takes place. Results of the investigation of vanadium in the molten state at about 2100 exp 0 C are in rather good agreement with values extrapolated from the results of Hoerz for vanadium in the solid state. Various methods of nitrogen determination are discussed. In experiments the best results were obtained with the Pt-capsule method and the Pt-capsule plus Pt-bath method. (ERA citation 05:036896)
