本文研究了FeO-UO_2-ZrO_2（惰性气氛）和Fe_2O_3-U_3O_8-ZrO_2（空气）体系。对于FeO-UO 2-ZrO 2系统，共晶温度被发现为1310°C，具有以下组分浓度（摩尔%）：91.8 FeO、3.8 UO 2和4.4 ZrO 2。对于Fe 2 O3-U3 O 8-ZrO 2系统，共晶温度被发现为1323°C，具有以下组分浓度（摩尔%）：67.4 FeO 1.5、30.5 UO 2.67和2.1 ZrO 2。测定了铁氧化物在以UO_2（ZrO_2，FeO）和UO_（2.67）（ZrO_2，FeO_（1.5））为基础的相中的溶解度极限。
The systems FeO-UO2-ZrO2 (in inert atmosphere) and Fe2O3-U3O8-ZrO2 (in air) were studied. For the FeO-UO2-ZrO2 system, the eutectic temperature was found to be 1310°C, with the following component concentrations (mol %): 91.8 FeO, 3.8 UO2, and 4.4 ZrO2. For the Fe2O3-U3O8-ZrO2 system, the eutectic temperature was found to be 1323°C, with the following component concentrations (mol %): 67.4 FeO1.5, 30.5 UO2.67, and 2.1 ZrO2. The solubility limits of iron oxides in the phases based on UO2(ZrO2,FeO) and UO2.67(ZrO2,FeO1.5) were determined.
