摘要：

Solubility of Fe2O3 and Cr2O3 powder to binary fused Na2O B2O3 salt system was measured at 1173 K in air. Basicity of the melt was continuously monitored by the basicity sensor with an oxide ion probe and zirconia oxygen probe. Basicity of the fused salt was varied from 10.3 to 14.5 by adding B2O3 powder. For the entire range of the tested basicity, solubility of Fe2O3 was one order of magnitude higher than that of Cr2O3. Solubility of both Fe2O3 and Cr2O3 decreased with increasing the basicity of the melt. From the solubility dependence on the melt basicity, both Fe2O3 and Cr2O3 are suggested to dissolve by the basic dissolution reaction.
