A bstract Samples of high‐heat duty, superduty, 60% Al 2 O 3 , 70% Al 2 O 3 , 90% Al 2 O 3 , fused‐alumina, kaolin base, kyanite base, chrome magnesite, silicon carbide, zircon, and chrome‐magnesite compositions were tested for reaction with MgO at temperatures of 2200°, 2600°, and 2800°F. (1205°, 1425°, and 1540°C.). Silicon carbide and zircon refractories showed a slight reaction at 2800°F. and none at 2600°F. or at 2200°F. Commercial grades of firebrick containing 60% or more of Al 2 O 3 in contact with powdered magnesia showed no reaction up to 2800°F.
