Tab.S1 - Summary table comparing critical aspects of different methods for synthesizing skutterudites Fig.S1. Room temperature X-ray diffraction patterns of skutterudites with nominal composition Yb0.75Ce0.25Fe3.5Co0.5Sb12 after (a) mechanochemical synthesis carried out for different durations (b)-(c) different sintering temperature for 30 min, 60 min powders and 15 min powder, respectively (d) after mechanochemical synthesis for 15 min and corresponding volumes sintered from this powder using the SPS method with different exposure times. Fig.S2. thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) for S15, S30, S60 Fig.S3. Components of thermal conductivity of (a) electronic thermal conductivity skutterudites (b) lattice thermal conductivity as a function of inverse temperature. The solid line is linearly fitting to the lattice thermal conductivity in temperature range from 323 to 473 K.
