Properties of periclase-carbon refractories containing metal powders
1989
The effect of the metallic additives (Al, Cr, and FeSi) on the properties of unfired periclase-carbon products was studied. It was shown that their presence decreases the degree of oxidation of graphite without decreasing the strength properties of the refractory. When heat treating the periclase-carbon specimens up to 1000°C, the effectiveness of the additives decreases in the following order: Al, Cr, FeSi. At 1400°C, the effectiveness of all the additives is virtually identical.
