ABSTRACT:
Fusion cast refractories are formed by first displacing the air from the mold cavity with an inert, heavy gas, preferably argon. The molten fusion cast refractory is then poured into the mold cavity and allowed to solidify. This procedure minimizes the evolution of gases from molds which have an organic binder and thus reduces the formation of pores in the solidified refractory.
