Abstract
Three batches of finely divided Nb3Al intermetallic powders obtained by calcium hydride reduction were studied for the contents of light elements (H, O, N, C, and S). The oxygen-containing phases present in the Nb3Al powder samples were determined. The oxygen contained in the powder was qualitatively and quantitatively divided into oxygen as a part of adsorbed water, oxygen as a part of surface organic compounds, and oxygen as a part of niobium oxides (NbOx) and aluminum oxides (Al2O3).
