Abstract

The low-temperature phase transitions of thermoelectric Zr ₄ Sb ₃ have been characterized using singlecrystal X-ray diffraction, electrical resistance, and thermal conductivity measurements. Room-temperature stable, disordered β-Zn ₄ Sb ₃ undergoes a phase transition at 254 K to ordered α-n ₄ Sb ₃ , which has an ideal composition Zn ₄ Sb ₁₀ . Below 235 K, a second low-temperature phase (α′-Zn ₄ Sb ₃ ) can be detected. The sequence of phase transitions β-α-α′ is reversible. The α-α′ transformation originates from a slight Zn deficiency with respect to Zn ₁₃ Sb ₁₀ Sb ₁₀ . The actual composition of n ₄ Sb ₃ is Zn ₁₃ -δSb ₁₀ .
