| 英文摘要 | The crystal structures of the zeta-phase and zeta'-phase have been determined by x-ray powder diffraction and refined by rietveld method. the space group of the zeta'-phase is p (6) over bar 2m with the lattice parameters a = 7.7710(1) and c = 2.8788(1) angstrom. the ideal formula is ag2ga (real composition ag2+xga1-x, x = 0.16) and the chemical formula per unit cell is z = 3. six ag atoms occupy the 3g positions with x = 0.63970(8) and the 3f positions with x = 0.30347(9), respectively. three ga atoms occupy the 2c and the 1b sites. the zeta-phase is obtained by quenching the sample containing 20 at.% ga from 500 degrees c to room temperature. its space group is close-packed hexagonal, p6(3)/mmc, and the lattice parameters are a = 2.8818(1) and c = 4.6956(1) angstrom. there are 2 atoms (1.5ag + 0.5ga) per unit cell, which occupy the 2c site statistically. the relation between the structures of the zeta- and zeta'-phase is discussed.
