ceramic

· JVASP-17840· USbAs

USbAs is a ternary ceramic compound belonging to the III-V semiconductor family, combining uranium, antimony, and arsenic in a crystalline structure. This material is primarily of research and development interest for advanced semiconductor and optoelectronic applications where extreme radiation hardness and high-temperature stability are required. While not yet widely commercialized, uranium-based compounds like USbAs are explored in nuclear physics, space electronics, and specialized detector systems where conventional semiconductors would degrade rapidly under neutron or gamma radiation.

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.
