摘要：
The nitride capacities (C(N3) = (%N)P(O3)3/4/P(N2)1/2) in CaO-Al2O3 melts were measured by a gas-slag equilibration technique, using CaO, Al2O3, and Mo crucibles in the temperature range from 1 723 to 1 923 K. The oxygen partial pressures measured by a solid electrolyte cell were controlled by N2-H2-H2O gas mixtures. It was found that the nitride capacities increased with increasing temperature and Al2O3 content in slag. Activity coefficients of AlN increased with decrease of Al2O3 content and temperature.
