· JVASP-123488· HfU3

HfU3 is a uranium-hafnium intermetallic ceramic compound that combines two dense, refractory elements into a single-phase material. This material exists primarily in research and experimental contexts, where it is being investigated for applications requiring extreme thermal stability, high density, and resistance to corrosion in nuclear or high-temperature environments. Its notable characteristics stem from hafnium's exceptional neutron absorption cross-section and uranium's density, making it of particular interest for specialized nuclear fuel forms or advanced shielding applications where conventional ceramics fall short.

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.
