Abstract: The EuI2-LiIand EuI2-NaIsystems were studied by differential thermal analysis (DTA) and X-ray powder diffraction.The phase diagram of EuI2-LiIis eutectic one.The results show that the eutectic point is at 385 ℃with molar composition 68.5% LiI.The phase diagram of EuI2(Nal is an eutectic point too, the eutectic point exists at 409 ℃with molar composition 32% NaI- In both two systems the crystal transitiori of EuI2 at 354 ℃ has been found.
