  Isothermal cross-section of the Ce–Pd–Ge phase diagram at 600°C

  摘要：

  The interaction of the components in the Ce-Pd-Ge system at 600 degrees C was investigated over the whole concentration range by X-ray powder and monocrystal diffraction, metallography, and X-ray microprobe analysis. The formation of the previously reported phases, CePdGe and CePd2Ge2, was confirmed and 15 new ternary compounds were observed. The crystal structures of the compounds Ce2PdCe6, Ce(Pd,Ge)(2), Ce3Pd20Ge6, CePd2Ge, Ce7Pd4Ge2 and CePd5Ge3 were determined. (C) 1998 Elsevier Science S.A.

  Phase relations in the ternary system Ce-Pd-Si have been established for the isothermal section at 800 degrees C based on X-ray powder diffraction and EMPA techniques on about 130 alloys, which were prepared by arc-melting under argon or powder reaction sintering. Eighteen ternary compounds have been observed to participate in the phase equilibria at 800 degrees C. Atom order was determined by direct methods from X-ray single-crystal counter data for the crystal structures of tau(8)-Ce3Pd4Si4 (U3Ni4Si4-type, Immm; a = 0.41618(1), b = 0.42640(1), c = 2.45744(7) nm), tau(16)-Ce2Pd14Si (own structure type, P4/nmm; a = 0.88832(2), c = 0.69600(2) nm) and also for tau(18)-CePd1-xSix (x = 0.07; FeB-type, Pnma; a = 0.74422(5), b = 0.45548(3), c = 0.58569(4) nm). Rietveld refinements established the atom arrangement in the structures of tau(5)-Ce3PdSi3 (Ba3Al2Ge2-type, Immm; a = 0.41207(1), b = 0.43026(1), c = 1.84069(4) nm) and tau(13)-Ce3-xPd20+xSi6 (0 <= x <= 1, Co20Al3B6-type, Fm (3) over barm; a = 1.21527(2) nm). The ternary compound Ce2Pd3Si3 (structure-type Ce2Rh1.35Ge4.65, Pmmn; a = 0.42040(1), b = 0.42247(1), c = 1.72444(3) nm) was detected as a high-temperature compound, however, does not participate in the equilibria at 800 degrees C. Phase equilibria in Ce-Pd-Si are characterized by the absence of cerium solubility in palladium silicides. Mutual solubility among cerium silicides and cerium-palladium compounds are significant where by random substitution of the almost equally sized atom species palladium and silicon is reflected in extended homogeneous regions at constant Ce content such as for tau(2)-Ce(PdxSi1-x)(2) (AlB2-derivative type), tau(6)-Ce(PdxSi1-x)(2) (ThSi2-type) and tau(7)-CePd2-xSi2+x. The crystal structures of compounds tau(4)-Ce similar to 8Pd similar to 46Si similar to 46, tau(12)-Ce similar to 29Pd similar to 49Si similar to 22, tau(15)-Ce similar to 22Pd similar to 67Si similar to 11, tau(17)-Ce similar to 5Pd similar to 77Si similar to 18 and tau(18)-CePd1-xSix (x similar to 0.1) are still unknown.
