Exploration of porous SiC nanostructures as thermal insulator with high thermal stability and low thermal conductivity

摘要

The crucial challenge for current nanoscale thermal insulation materials,such as Al_2O_3 and SiO_2 aerogel composites,is to solve the trade-off between extremely low thermal conductivity and unsatisfied thermal stability.Typical high-temperature ceramic SiC possesses excellent mechanical properties
