· JVASP-14795· PuB2

PuB2 is a plutonium diboride ceramic compound belonging to the refractory boride family, engineered for extreme-environment applications requiring exceptional hardness and thermal stability. This material is primarily investigated in nuclear fuel development, advanced reactor systems, and specialized defense applications where its chemical inertness and resistance to thermal cycling are valued. PuB2 represents a research-driven material system rather than a commercial commodity, selected for its superior performance in harsh nuclear and high-temperature contexts where conventional ceramics would degrade.

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.
