The effect of Ti(C, N) on properties of low-carbon MgO-C bricks was investigated. The phase composition and the microstructure of the matrix of low-carbon MgO-C brick containing Ti(C, N) were studied by XRD and SEM analysis together with EDS. The results showed that Ti(C, N) distributed in the matrix of lowcarbon MgO-C brick uniformly after being treated at 1600℃ for 3h in coke powder bed, and Ti(C, N) and MgO formed a solid solution. After the treatment at 1600℃ for 3h in coke powder bed, the bulk density and cold crushing strength of low-carbon MgO-C brick with Ti(C, N) decreased, and the apparent porosity and linear change rate of specimens increased. The oxidation resistance of low-carbon MgO-C brick with Ti(C, N) was superior to that of low-carbon MgO-C brick with no additives, but inferior to that of low-carbon MgO-C brick with Al powder. The slag resistance of the specimen with Ti(C, N) was excellent as well.
