Title: Effects of Al<sub>2</sub>O<sub>3</sub>, CaO and Cr<sub>2</sub>O<sub>3</sub>on liquidus temperatures of Fe–Mg–Si–O slags
Abstract: Experimental studies have been carried out to determine phase equilibria in the Fe–Mg–Si–Al–Ca–Cr–O system in air and in reducing atmospheres. The univariant lines between spinel and tridymite primary phase fields, and between the pyroxene and tridymite primary phase fields in the Fe–Mg–Si–O system with and without CaO, Al2O3 and Cr2O3 addition have been determined. The measurements demonstrate clearly that the presence of Al2O3 and CaO in the system lowers the liquidus in the silica primary phase field. The study also confirms that lowering the oxygen potential in the system lowers the liquidus temperatures for Fe–Mg–Si–Al–Cr–Ca–O slags.
