The mechanism and state of formation for these two paths are different. Atthe slag-coke interface, TiC is formed first, and the unhomogeneous interstitial solidsolution Ti(C, N) is then formed by nitrogen atom diffusion from furnace gas intoTiC lattice. The slag basicity and temperature are extremely influential in the forma-tion of Ti(C, N). The larger the slag-coke interface is, the more favourable the for-mation of Ti(C, N) will be.
