Special silica bricks containing Cr_2O_3 8% have the property of higher resistance to iron oxide absorption than common silica bricks, retaining, however, the characteristics of silica bricks which have high-softening temperature, strong compressive strength, and high thermal expansion. The characteristics of these bricks are as follows ; (1) Absorption of Fe_2O_3 in these bricks are nearly stopped only at the surface layer. (2) Decrease of refractoriness by the absorption of Fe_2O_3 in these bricks are smaller than common silica bricks. The results of the practical test of these bricks are as follows ; (1) Corrosion of these bricks is decreased 36∿64% than high-Al_2O_3 chamotte bricks, when on lower part of the side walls of the up-take is used. (2) Corrosion of these bricks is decreased 59∿70% than common silica bricks, when they are used on the walls of the slag-chamber, (3) Corrosion of these bricks is decreased 50% than common silica bricks, when they are used on the slag-chamber arch.
