The present study investigated the relationship between sulfide capacity and the average nonbridging oxygens to tetrahedral cations (NBO/T) of CaO‐SiO₂‐Al₂O₃‐MgO slags. The sulfide capacity and NBO/T increase with increasing Al₂O₃/SiO₂ ratio and X_CaO due to increasing basicity. The inflected dependence of sulfide capacity and NBO/T observed at a eutectic composition. Thermodynamic investigations revealed that the inflected dependence is caused by the effects of mixing enthalpy and entropy components in eutectic composition. Quantitative analysis of sulfide capacity and NBO/T revealed a proportional linear relationship between the two variables. Based on these experimental results, the corresponding structure‐property relationships concerning sulfide capacity, viscosity, and stability are discussed in detail.

基于离子结构考虑的铝硅酸盐矿渣的硫化能力研究

本研究研究了CaO-SiO ₂ -Al ₂ O ₃ -MgO渣的硫化容量与平均非桥连氧与四面体阳离子（NBO / T）的关系。硫化物容量和NBO / T随Al ₂ O ₃ / SiO ₂比和X _{C aO的}增加而增加由于增加了基础性。在低共熔组成下观察到的硫化物容量和NBO / T的变化依赖性。热力学研究表明，弯曲的依赖性是由共晶成分中的焓和熵成分混合引起的。硫化物容量和NBO / T的定量分析揭示了两个变量之间的比例线性关系。根据这些实验结果，详细讨论了与硫化物容量，粘度和稳定性有关的相应的结构-性质关系。
