Uranium-Uranium Monoarsenide Phase Diagram

Uranium‐uranium monoarsenide phase boundaries are deduced from thermal analyses and from x‐ray diffraction and microscopic analyses of quenched products. The uranium‐uranium monoarsenide eutectic occurs at with a composition near pure uranium. Uranium solubility in the UAs phase does not exceed 0.15%. The highest melting point observed with the UAs (+U) phase is 2705°C.
