Effect of addition of non-oxides on the slag corrosion resistance of MgO-Al2O3 refractories

Research output: Contribution to journalConference articlepeer-review


Various non-oxides, such as SiC, Si3N4 and AlN were added to MgO-Al2O3 refractory, and the effect on the slag corrosion resistance was investigated. The specimens were prepared by a spark plasma sintering (SPS) method. Slag corrosion tests were carried out using a button method under a reducing atmosphere. Improvement in corrosion resistance was confirmed for the SiC-added specimens, and the addition of nitrides, however, resulted in deterioration. Wettability was also examined, and the compositional dependence was not observed in contact angle. Quantitative relation was not found between contact angle and penetration depth.
