Structural transformations during the synthesis of mayenite (Ca12Al14O33) were investigated. The samples were prepared by a solid–state reaction and the transformations were researched by means of XRD, Rietveld analysis, SEM, and Raman spectroscopy. The three key phases (CaAl2O4, Ca3Al2O6, Ca5Al6O14) were identified and their role in the mayenite formation was assigned. The optimal low temperature pathway of the mayenite synthesis involving Ca5Al6O14 intermediate was proposed.
