Structures of ζ and ζ′ Phases in the Ag—Ga System.

Abstract

Structure D 2000Structures of ζ and ζ' Phases in the Ag-Ga System. -As revealed by Rietveld refinement of powder XRD data the ζ' phase of the title system (Ag2+xGa1-x, x = 0.16) crystallizes in the space group P62m with Z = 3. The ζ-phase crystallizes in the close-packed hexagonal space group P63/mmc with Z = 2. -(ZHANG, Y.; LIU, Q. L.; LI, J. B.; LIANG*, J. K.; LUO, J.; LIU, F. S.; XIAO, Y. G.; RAO, G. H.; J.
