HfBe13
ceramic· 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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
