Abstract
Ternary Nd-Pr-Sb alloys were studied using X-ray powder diffraction an d optical and electron microscopy. (Nd, Pr)2Sb (tI12 - La2Sb type), (N d, Pr)4Sb3 (cI28 - anti-Th3P4 type), (Nd, Pr)Sb (cF8 - NaCl type) and (Nd, Pr)Sb2 (oC24 - SmSb2 type) show complete solubility between Nd an d Pr. The variation of the lattice parameters as a function of the Nd to Pr ratio was determined. In addition, the alloy Nd0.475Pr0.475Sb0.0 5 was investigated by differential thermal analysis (DTA). The results obtained confirm a previous thermodynamic prediction of the Nd-Pr-Sb phase equilibria.
