ABSTRACT:
A monolithic refractory powder mixture containing from 2 to 3 wt % of spheroidized refractory particles having a mean particle size of at most 30 .mu.m of at least one member selected from the group consisting of alumina cement, alumina, titania, bauxite, diaspore, mullite, aluminous shale, chamotte, pyrophyllite, sillimanite, andrewsite, silica rock, chromite, spinel, magnesia, zirconia, zircon, chromia, silicon nitride, aluminum nitride, silicon carbide, boron carbide, zirconium boride and titanium boride, and having a cone flow value of at least 180 mm when a refractory mixture having the powder mixture kneaded by an addition of 6 parts by weight of water per 100 parts by weight of the powder mixture, is cast into a cone-shaped mold with a dimension of 70 mm.o slashed.-100 mm.o slashed..times.60 mm and left to stand for 60 seconds without exerting vibration after removing the cone-shaped mold.
