Phase Equilibria in the Al-Nd-Sb System at 500 ℃

摘要

The Al-Nd-Sb phase diagram over the whole concentration region at 500 ℃ has been determined with the use of powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive analysis. A new ternary compound ～Al6Nd28Sb66 (space group Imm2, a=1.5191(1) nm, b=1.9914(2) nm, c=0.4377(1) nm) with La6MnSb15-type has been found.
