ceramic

· JVASP-14756· USb

USb is a uranium-bearing ceramic compound in the uranium boride family, characterized by high density and significant structural rigidity. It is primarily investigated in nuclear materials research and advanced refractory applications where extreme temperature stability and radiation resistance are critical. This material is notable for its potential in nuclear fuel applications and high-temperature structural components, though its uranium content restricts its use to specialized industrial and defense contexts where regulatory approval and security protocols can be maintained.
