Phase composition of niobium pentoxides doped with Mg2+ and Gd3+cations
Abstract. In this work the XPA method and IR spectroscopy have been used to study the phase composition of (Nb)2(O)5:Mg and (Nb)2(O)5:Gd alloys in the concentration range of 0.05-1 mass.% Mg in (Nb)2(O)5 and 0.1-4 mass.% Gd in (Nb)2(O)5. The content of magnesium in niobium pentoxide at which the second phase, Mg(Nb)2(O)6, begins to form has been determined. It has been shown that in the studied gadolinium concentration range there exists only a low-temperature (Nb)2(O)5 modification.
