“…System CaO-SiO 2 -Al 2 O 3 (C-A-S) has a great practical importance. When phase regions of C-A-S system were projected to the Gibbs triangle, it has given 117 two-, 163 one-and 45 zerodimensional concentration fields [9][10][11][12][13]. The crystallization paths and the formation of microconstituents in phases assemblage have been analyzed for the surfaces of CaO, 3CaOSiO 2 and 3CaOAl 2 O 3 primary crystallization.…”

The aim of this work is to assemble the computer models of phase diagrams (PD) for the typical ternary systems and to examine the processes of crystallization on its base. Spatial schemes of mono-and invariant equilibria have been used for it. Analysis of concentration fields, obtained by the projection of the surfaces on the Gibbs triangle, allows establish the boundaries of phase regions (located above the considered fields), the sequence of phase transformations and microstructural elements for the solidification of the initial melt at equilibrium condition. Concentration fields have been analyzed by means of mass balances for their centers of masses. Based on this technology, the research identifies concentration fields with coinciding sets of phase reactions and microconstituents, and the fields with individual characteristics.

“…Let's consider the system CaO-SiO 2 -Al 2 O 3 , that has a great practical importance. The coordinates of binary and ternary invariant points are given as an initial data for the computer model of its phase diagram, simulated by means of kinematic surfaces [1]. Simulation of 3D model was complicated by the absence of unambiguous data both for the bounding binary systems and for the liquidus of ternary system.…”

The problems of computer model simulation of CаO-SiO2-Al2O3 system are considered. The crystallization scheme and sets of microstructure elements are analyzed for the fields of liquidus CaO, 3CaO*SiO2, 3CaO*Al2O3. The concentration fields both with individual set of microstructure elements and the fields without the unique crystallization scheme and microstructure set were found. The crystallization stages for given compositions are illustrated by the mass balance diagrams.

The phases trajectories in the fields of primary crystallization of cristobalite (SiO 2 cr ), tridymite (SiO 2 tr ), mullite (3Al 2 O 3 ⋅2SiO 2 ) and in a field of liquid immiscibility are analyzed on a basis of computer model for T-x-y diagram of SiO 2 -Al 2 O 3 -CaO system. The concentration fields with unique set of microconstituents and the fields without individual crystallization schemes and microconstituents are revealed. Keywords: phase diagram, crystallisation path, SiO 2 -Al 2 O 3 -CaO system, computer model
