(Hf 0.2 Zr 0.2 Ta 0.2 Nb 0.2 Ti 0.2 )C high‐entropy ceramics with low thermal conductivity

Abstract A novel high‐entropy carbide ceramic, (Hf 0.2 Zr 0.2 Ta 0.2 Nb 0.2 Ti 0.2 )C, with a single‐phase rock salt structure, was synthesized by spark plasma sintering. X‐ray diffraction confirmed the formation of a single‐phase rock salt structure at 26‐1140°C in Argon atmosphere, in which the 5 ... View More
