· JVASP-20127· UBe13

UBe13 is an intermetallic ceramic compound in the uranium-beryllium system, representing a high-density ceramic material combining the refractory properties of uranium with beryllium's lightweight characteristics. This material is primarily of research and specialized defense/nuclear interest, valued for applications requiring extreme density, thermal stability, and radiation resistance in environments where conventional ceramics or metals prove insufficient. Its use is highly restricted and limited to classified or specialized nuclear and aerospace programs where its unique combination of properties—particularly density and thermal/radiation performance—justifies the material handling complexity and regulatory constraints.
