The phase diagram of the EuI{sub 2}-KI binary system was studied by differential thermal analysis (DTA) and X-ray powder diffraction (XRD). The phase diagram of the EuI{sub 2}-KI system shows the existence of one congruently melting compound, KEu{sub 2}I{sub 5}, and one incongruently melting compound, K{sub 4}EuI{sub 6}. There are two eutectic points located at 465 C, 20 mol% KI and 439 C, 60 mol% KI, respectively.
