ABSTRACT OF THE DISCLOSURE The invention relates to precluding the short- comings intrinsic to the conventional unburned carbon- containing refractory bricks, i.e., oxidization under high temperature conditions and the incidental de- carbonization, the phenomenon of exfoliation and detachment of the fragile layers, and more particularly to obtaining thereby unburned carbon-containing refractory bricks having the high properties by causing refractory brick material comprising substantially more than 1 weight % carbon to contain 1-10 weight % aluminum powder and/or magnesium powder each independently or in a mixture thereof, and/or 0.5-6 weight % silicon powder.
