ABSTRACT:
A refractory composition for use in contact with molten aluminum alloys containing a refractory aggregate, a binder and an additive for imparting aluminum resistance to the refractory composition, the additive comprising synthetic calcium fluoride containing aluminum borate aggregate consisting essentially of 10 to 50% by weight boron oxide, 10-50% by weight of aluminum oxide, and 25-75% by weight calcium flouride. The synthetic aggregate may be prepared by blending boric acid, aluminum oxide, and fluorspor and firing the resultant blend at a temperature above 800.degree. C. to form a synthetic aluminum borate having calcium fluoride contained in its insoluble structure.
