The phase diagram of the Sc-Zn system has been investigated using differential thermal analysis (DTA), metallographic analysis, X-ray diffraction (XRD) and electron microscopy. The Sc-rich side of the system (0 to 40 at.% Zn) has not been studied owing to the high reactivity and contamination of the samples by the container material (Mo). Five intermediate phases have been found: ScZn (CsCl-type), ScZn2 (AlB2-type), Sc3Zn17 (Ru3Be17-type), ScZn12 (ThMn12-type) and Sc13Zn58 (Gd13Cd58-type), which was not previously known. When comparing this system with the Y-Zn or other R-Zn systems, a clear difference, especially concerning the number of intermediate phases formed, which in the case of Sc is much lower, emerges.
