Abstract :
CoSb3 micrometer powder was synthesized by solid-state reaction using high purity powder of Co, Sb as the starting materials. CoSb3 nano-powder and block material with nanostructure were prepared by high-energy ball-milling and by Spark Plasma Sintering (SPS), respectively. The influence of mass ratio of big balls and small balls, milling speed and time on particles size of CoSb3 powder, and sintering temperature and time on grains size of CoSb3 were investigated. The influence of nanostructure on thermal transport properties of CoSb3 was also studied.
