ABSTRACT:
An additive to foundry sand molding and core aggregates used to produce cores and molds which improves the quality of castings by reducing thermal expansion and gas defects. The additive comprises a composition containing from about 15% to about 95% titanium dioxide (TiO.sub.2). Preferably, the composition of the additive comprises about 2-38% silicon dioxide (SiO.sub.2), about 5-40% ferric oxide (Fe.sub.2 O.sub.3), about 15-95% titanium dioxide (TiO.sub.2), and about 2-45% aluminum oxide (Al.sub.2 O.sub.3).
