Platinum-vanadium and nickel baths for inert gas fusion oxygen determination.
Anal Chem 1974 Aug; 46(9):1191-1194
Low and inconsistent results were encountered with an unalloyed platinum bath when analyzing thoriated and zirconiated tungsten for oxygen content by inert gas fusion. Data are given to show that vanadium additions to platinum baths made the recovery of oxygen easier from both of these tungsten-base alloys and also from titanium and fs-85 niobium alloys. Data are given to show that a nickel bath and wrap was superior to platinum for determining oxygen in zirconium and beryllium. In addition, a nickel bath and wrap works well for titanium and tungsten but not for fs-85 niobium alloy. The importance of carbon solubility in the melt and the role of tin are discussed.
