· JVASP-123462· U3As

U3As is a uranium arsenide ceramic compound belonging to the actinide intermetallic family, characterized by a dense crystalline structure. This material is primarily of research and specialized nuclear applications interest rather than mainstream industrial use, with potential applications in nuclear fuel development, neutron absorber studies, and high-temperature ceramic research where uranium-bearing compounds are systematically evaluated for their thermal and radiation properties.

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.
