  • Corrosion resistant castable refractory mix
    Patent number: 4088502
    Abstract: A corrosion resistant castable refractory mix is provided comprising a particulate mixture capable of mixture with water to form a castable refractory having enhanced corrosion resistance to molten aluminum. The mixture consists essentially of 20-34 parts by weight calcium aluminate, 6-10 parts by weight of a zinc borosilicate frit, and 60-70 parts by weight fused silica. The zinc borosilicate frit consists essentially of 50-60% by weight zinc oxide, 20-40% by weight boron oxide, 8-12% by weight silicon oxide, and 0-10% by weight aluminum oxide with less than 0.5% by weight of other impurities. The refractory mix contains not greater than 1% by weight impurities.
