| Abstract: | Using equilibrium experimental data of CO+N2 and CaO+ SiO2-Al2O3 molten slags, this paper discusses the thermodynamics of solution reaction of nitrogen in the slags base don the bond theory of melted slags. The results show that nitrogen replaces bridging oxygen ions and exists as Si-N-Si, Al-N-Al and Si-N-Al in the CaO-SiO2-Al2O3 slags. Empirical equations are derived to estimate the activity coefficients of silicon and aluminum nitrides in the slags. |
