The isothermal section of the phase diagram of the Zr-Ni-Sb ternary system at 870 K in the whole concentration range has been constructed by means of X-ray and metallographic analyses. Eight ternary intermetallic compounds Zr6NiSb2 (
The new antimonides ZrNiSb and HfNiSb: Synthesis, structure, and properties in comparison to ZrCoSb and HfCoSb

The antimonides ZrNiSb and HfNiSb were prepared by arc-melting of stoichiometric mixtures of Zr, ZrSb2 and Ni, and Hf, HfSb2 and Ni, respectively. Unlike ZrCoSb and HfCoSb, which form the LiAlSi structure type, ZrNiSb and HfNiSb crystallize in the TiNiSi type. The lattice dimensions are a = 672.7(2) pm, b = 416.43(8) pm, c = 753.8(1) pm, V = 211.16(7) × 106 pm3 for ZrNiSb and a = 662.3(5) pm, b = 413.3(3) pm, c = 746.8(8) pm, V = 204.4(3) × 106 pm3 for HfNiSb (space group Pnma). Whereas no Zr-Zr contacts a consequence of the different numbers of valence electrons. The structural differences come along with a drastic change in the electronic structure and in the physical properties: ZrNiSb exhibits metallic behavior, in contrast to the not conducting ZrCoSb.
SYNTHETIC AND STRUCTURAL STUDY OF THE ZIRCONIUM-ANTIMONY SYSTEM.

Ten phases have been obtained in the Zr-Sb system using arc-melting, annealing, powder sintering, vapor-phase transport, vaporization, and metal flux methods. In addition to the previous reported compositions (and structure types), Zr//3Sb(Ni//3P), Zr//5Sb//3(Mn//5Si//3), and ZrSb//2(ZrSb//2), there also exist Zr//2Sb(La//2Sb), high temperature Zr//5Sb//3(Y//5Bi//3), ZrSb//1// minus //x(FeSi), ZrSb(ZrSb-Cmcm), and low temperature ZrSb//2// minus //x (PbCl//2). There are also phases of unknown structure near the Zr//2Sb composition at high temperatures and for Zr//2Sb//3 that are provisionally primitive orthorhombic and tetragonal, respectively. The Mn//5Si//3-type phase Zr//5Sb//3// plus //x is a true binary and nonstoichiometric over the ranges 0. 0 less than equivalent to x 0. 4. Guinier lattice constant data are reported for all the phases.
