Abstract: The phase diagram of EuI2-RbIbinary system has been studied by DTAand X-ray powder diffraction.It is a complicated eutectic system with four compounds─two congruent melting compounds RbEu2I5 and RbEuI3 and two incongruent melting compounds Rb3EuI5 and Rb4EuI6.The structure of Rb3EuI5 belongs to a cubic system with a=1.0124(1)nm, and Rb4EuI6 belongs to a tetragonal system with a=1.3719(5)nm, c=0.6458(5)nm.

Key words: Binary system, Phase diagram, X-ray powder diffraction
