Abstract in another language

Compositions of coexisting liquids in teh CaO-SiO2-TiO2-Al2O3 system at 1600°C have been determined. In teh Al-free ternary system, the msicibility gap is modelled in detail with weighted extrapolation of binary excess Gibbs free energy terms. Addition of few wt% Al2O3 reduces dramatically the extent and consolute temperature of the solvus. Extrapolations of the CaO-SiO2-TiO2 model parameters to the Al-bearing system without additional corrections disagree with experiments. However, possible procedures for the expanded extrapolation in the four component system are discussed.
