This is the authors' abstract. We don't add key points for this paper.

A computer 3D-model was presented for the isobaric phase diagram of the ZrO2–SiO2–Al2O3 system with the formation of the ZrSiO4 and Al6Si2O13 compounds. Its geometric structure was derived through the sequential construction of a scheme of phase reactions, including all polymorphic transitions in the subsolidus and the rearrangement of the interaction of binary compounds, as well as zirconium and aluminum oxides; its transformation into a scheme of uni- and invariant states in the tabular and graphical (3D) forms; and the construction of a prototype and its transformation into a spatial model of the phase diagram of the real ZrO2–SiO2–Al2O3 system. Features of the iso- and polythermal sections of the phase diagram of the considered system, which were calculated using the thermodynamic NUCLEA database, were discussed in comparison with the sections of the obtained 3D-model.
