The article is devoted to the study of the preparation and stabilization of pure cubic phase of tricalcium aluminate C₃A. The findings from the literature and several experimental trials have been summarized. Based on these findings, the synthesis of C₃A was realized, and high purity of this mineral was achieved. Furthermore, the influence of foreign ions, mainly in the form of potassium oxide K₂O combined with Na₂O in the form of sodium oxide on the crystal structure was investigated. The transformation of the cubic phase of C₃A into an orthorhombic phase was observed when the amount of these ions in the structure was changed.
