Formatted abstract
The phase equilibria in the ZnO–‘FeO’–Al2O3–CaO–SiO2–Na2O (K2 O) system have been determined experimentally in equilibrium with metallic iron. Pseudoternary sections ZnO–‘FeO’–(Al2O3zCaOzSiO2) for CaO/SiO250?71 (weight), (CaOzSiO2)/Al2O355?0 (weight) and fixed Na2O or K2O content have been constructed. It has been found that the addition of 1?0 wt-%Na2O or K2O does not introduce any new primary phases in the composition range investigated. The
presence of 1?0 wt-%Na2O or K2O in the liquid phase extends the wustite primary phase field and reduces the size of the spinel primary phase field. Liquidus temperatures are slightly increased in the wustite primary phase field and decreased in the spinel primary phase field by addition of 1?0 wt-%Na2O or K2O. Neither Na2O nor K2O is detected in the wustite or spinel solid solutions.  The presence of 1?0 wt-%Na2O or K2O in the slag does not affect the partitioning of the ZnO between the solid (wustite or spinel) and liquid phases.
