UCr4C4
metal· UCr4C4
UCr4C4 is a uranium-chromium carbide intermetallic compound belonging to the family of refractory metal carbides and actinide-bearing ceramics. This is a research-phase material studied primarily for its potential in extreme-environment applications where nuclear fuel compatibility, thermal stability, and hardness are critical; it represents exploration into advanced nuclear materials and high-temperature refractory systems rather than a widely commercialized engineering alloy.

Export Control
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.
