Formatted Abstract/Summary
An integrated research program is under way to develop a thermodynamic database for the Al2O3-CaO-FeOFe2O3-NiO-MgO-SiO2 chemical system. The program incorporates experimental and thermodynamic modelling studies. The NiO-MgO-SiO2 and NiO-CaO-SiO2 systems were experimentally investigated and reported and a thermodynamic database for the NiO-CaO-MgO-SiO2 system was developed.

High-temperature equilibration and rapid quenching techniques were used to study the phase equilibria in the NiOMgO-SiO2 and NiO-CaO-SiO2 systems in air. The compositions of phases were measured accurately using electron probe X-ray microanalysis (EPMA). Selected experiments were carried out to resolve discrepancies in the available literature data.

Computerized thermodynamic databases for the liquid slag and solid oxide phases in the NiO-CaO-MgO-SiO2 system were developed by critical evaluation/optimization of all available phase equilibrium and thermodynamic data. The Modified Quasichemical Model was used for the slag (molten oxide) phase. The models based on the Compound Energy Formalism were developed for the olivine, spinel and pyroxene solid solutions.
