Results of a study of the effect of antioxidant additives, i.e., metallic aluminum and titanium diboride, on the quality parameters of periclase-carbon ladle refractories are presented. Laboratory studies have shown that the addition of the studied antioxidants into the batch increases the strength and lowers the porosity of the specimens. The size of the decarburized layer due to the addition of metallic aluminum and titanium diboride is virtually the same, but the use of TiB2 adds additional strength to the decarburized and transition layers of the specimens. It is recommended that pilot tests be performed for joint introduction of the additives.
