a Temperature-dependent thermal conductivity (κ). Data for the sample prepared by arc melting is included for comparison31. b Temperature-dependent lattice and bipolar thermal conductivity (κL + κbip). c Comparison of κL at 873 K for Zr0.75Hf0.25NiSn0.99Sb0.01 samples sintered at various temperatures. d Phonon dispersion of ZrNiSn (black solid line) and Zr27Ni28Sn27 (blue color).
