· JVASP-20221· HfBe13

HfBe₁₃ is an intermetallic ceramic compound combining hafnium and beryllium, belonging to the family of refractory metal beryllides. This material is primarily explored in advanced materials research for extreme-temperature and neutron-rich environments where conventional ceramics and metals reach their limits. Industrial applications are limited and largely experimental, focused on aerospace propulsion systems, nuclear reactor components, and high-energy physics applications where exceptional thermal stability and low neutron absorption are critical advantages over conventional refractory oxides and carbides.
