摘要	We herein show that by integrating nano-scale phonon-scattering mechanisms, such as interfaces and stacking faults thermal resistances in porous nano-SiC, this outstanding material (with intrinsic very high thermal conductivity) could demonstrate promising thermal insulation property. Porous nano-SiC prepared at 1,500 degrees C exhibits a specific balanced mechanical strength (compressive and flexural strength are 26 and 13 MPa, respectively, with 57% porosity) and extremely low thermal conductivity (2 W m(-1) K-1 at 300 K); and sample sintered at 1,800 degrees C shows excellent mechanical strength but relatively high thermal conductivity. Our work reports the novel low thermal conductivity of porous nano-SiC for the first time.
