Recrystallization studies were conducted on pure Nb as a function of degree of formation, time, and temperature. The annealing behavior of Nb is of interest because of grain-size control and an insight into high temperature atomic mobility. Niobium has poor oxidation resistance above 400 deg C and even at pressures of 10/sup -4/ mm Hg, the metal readily oxidizes at 1200 deg C. Gas analysis on Nb was completed. Niobium samples were analyzed by vacuum fusion methods using baths of iron, nickel, or platinum. The most promising results were obtained with platinum baths. (H.G.G.)
