Phase equilibriums and structure transformations in the CeO2–Er2O3 system have been studied within 1500–600 °C in the full concentration range using XRD and petrography methods. It was established that the system is characterized by the formation of solid solutions on the basis of cubic modification of Er2O3 (C-type) and fluorite CeO2 (F-type). Solubility limits and concentration dependences of lattice parameters were determined for the phases forming in the system.

氧化铈和二氧化铈在1500–600°C温度范围内的空气中的相互作用

使用X射线衍射和岩石学方法研究了CeO 2 –Er 2 O 3系统在1500–600°C的温度范围内的相平衡和结构转变。已经确定该系统的特征在于基于Er 2 O 3(C型)和萤石CeO 2(F型)的立方改性形成固溶体。确定了在系统中形成的相的晶格参数的溶解度极限和浓度依赖性。
