Abstract Scope In this work Thermo-Calc software was used to calculate the phase diagram of the Fe-Si system. The deduced phase diagram includes twenty fields, where three fields represent pure phases; two solid solutions and a liquid phase. There are several fields of two co-existing phases; mixed solid phases, and mixed solid with liquid phases. A set of eutectic and eutectoid points were found, where transformation reactions and temperatures were identified. The results were compared with results in the literature and good agreements with some differences were found. This study is a step to understand the phase diagram of Ca-Fe-Si system for refining metallugical grade silicon (MG-Si).
