Abstract

The equilibria of Al and Ca between silicon alloy and the SiO₂-Al₂O₃-CaO ternary slags were investigated using graphite crucible at 1550°C. With the increase of Al₂O₃ content and CaO content in the slags, the Al and Ca contents increase respectively. The variation of the impurities is also affected by the silica content in slag, which provides the oxidant during the oxidation refining process. The distributions of the impurities Al and Ca in silicon were given in terms of isoconcentration curves for Al and Ca in the ternary slags of SiO₂-Al₂O₃-CaO. The present experimental work provides available data to analyze the action of Al and Ca during the oxidation refining process for silicon alloy.
