· JVASP-119049· U8NiSe17

U8NiSe17 is an intermetallic compound combining uranium, nickel, and selenium—a research-phase material within the family of ternary metal selenides. While not widely commercialized, this composition represents exploration into high-density metallic compounds with potential for specialized applications requiring uranium-based metallurgy, such as nuclear fuel matrices, shielding components, or advanced catalytic systems where the unique electronic and structural properties of mixed-valence uranium systems may offer advantages.

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.
