摘　　要：基于热力学与矿物学原理,利用热力学数据库软件Factsage7.0探究了Fe2O3-Cr2O3-NiO-MnO体系中各组分含量的变化对该系黑色陶瓷颜料中着色尖晶石析出的影响规律。结果表明,Fe2O3-Cr2O3-NiO-MnO体系在凝固过程中析出的着色尖晶石相主要为FeCr2O4、NiCr2O4和Fe3O4,开始析出温度为2130 K;体系中Fe2O3、Cr2O3、NiO、MnO等组元含量的变化对着色尖晶石的析出行为有明显的影响作用。Based on the thermodynamic and mineralogical principles,the thermodynamic database software Factsage7.0 was used to explore the influence of content change of each component in the Fe2O3-Cr2O3-NiO-MnO system on the precipitation of coloring spinels in the corresponding black ceramic pigment.The results show that the precipitated coloring spinel phases are mainly FeCr2O4,NiCr2O4 and Fe3O4 during the solidification process of the Fe2O3-Cr2O3-NiO-MnO system,and the initial precipitation temperature is 2130 K.The content change of Fe2O3,Cr2O3,NiO and MnO in the system has a great influence on the precipitation behavior of coloring spinels.
