Nitrogen solubility in its different forms has been determined for the CaO-CaF2-Al2O3 system at 1773 K. Carbonate ions solubility has also been determined for the same temperature. Free incorporated nitride depend on the slag structure and its interaction with other cations. It is shown that nitrogen solubility does not depend on the activity of a single component. Flourine ions behave in a similar way as the do in the ternary silicate system CaO-CaF2-SiO2, liberating both oxygens and incorporated nitride from the networks. The effect of addition of silica, titania and barium chloride to the system on nitrogen solubility has been determined.
