摘要
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; aCaO = 0.0407; aSiO2 = 0.5268; aAl2O3 = 0.00003, aTiO2 = 0.0005)). A corrected phase diagram is presented. © 2013 Allerton Press, Inc.
