Abstract

The CaO · SiO2-CaO · Al2O3 · 2SiO2-CaO · TiO2 · SiO2 system is analyzed. Thermodynamic analysis of monovariant and invariant solidification shows that, for invariant equilibrium and for solidification along the boundary curve between the solidification fields of anorthite and sphene, peritectic processes are observed. The invariant-state parameters of the system are determined: t = 1513 K; a CaO = 0.0407; \(a_{SiO_2 } = 0.5268\); \(a_{Al_2 O_3 } = 0.00003\), \(a_{TiO_2 } = 0.005\)). A corrected phase diagram is presented.
