| 中文摘要 | The crucial challenge for oxide thermal insulators, such as Al2O3 and SiO2 nano-particle aggregates, is to solve the trade-off between extremely low thermal conductivity and unsatisfied sintering stability. We herein report the ultra-low thermal conductivities (0.068-0.1 W m(-1) K-1) of beta-SiC nanoparticle (similar to 35 nm) packed beds. The breakthrough is realized by multiple heat blocking mechanisms in the nanostructures. The samples also possess good thermal stability as high as 1500 degrees C. Our results provide a new strategy to explore ultra-low thermal conductivity materials with excellent thermal stability, regardless of their high intrinsic lattice thermal conductivities.
