· JVASP-78770· PuSb

PuSb is a plutonium-antimony intermetallic ceramic compound, representing a dense actinide material studied primarily in nuclear materials science and weapons physics research contexts. This material is notable for its extreme density and potential thermal properties, making it relevant to specialized nuclear applications where high atomic mass and radiation resistance are critical. PuSb belongs to the broader family of actinide compounds with limited civilian applications due to regulatory and proliferation concerns, though it remains significant in fundamental materials research and historical nuclear programs.

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.
