· JVASP-123533· U3Ta

U3Ta is a uranium–tantalum intermetallic ceramic compound belonging to the refractory metal family, typically studied for extreme-environment applications requiring both high density and thermal stability. This material represents an experimental/research-phase composition rather than a widely commercialized engineering ceramic; it is of interest in nuclear fuel matrices, high-temperature structural applications, and specialized defense/aerospace contexts where uranium-based ceramics offer unique combinations of density and refractory behavior. Compared to conventional tungsten or molybdenum-based ceramics, uranium compounds like U3Ta provide alternative solutions for applications demanding extreme thermal resistance or radiation shielding in demanding service environments.

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.
