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.
