摘要

Hafnium carbide (HfC) have attracted growing interests from research of ultra-high temperature ceramics (UHTCs) field. In this paper, we investigated the synthesis and high temperature stability of one-dimensional (1D) HfC and the core-shell HfC nanwoires/pyrolytic carbon (HfC_NWs/PyC). Results exhibited that HfC_NWs with diameter of 200–300 nm could keep their morphological and structural stability at 2100 ℃, and PyC improved the stability of HfC_NWs under high temperature conditions. Our work could not only provide theoretical basis for HfC_NWs reinforced carbon or ceramic-based composites, but also propose a deep thinking of the stability of nanomaterials under ultra-high temperature conditions.
