摘要：
By means of thermal and X-ray analyses with oxygen control, 14 phase diagrams of the systems MgF2-(Y, Ln)F3 have been obtained, where Ln are all lanthanides except Pm and Eu. All the systems are eutectic. Solid solutions up to 12 mole% MgF2, which decompose by the eutectoid scheme, were detected based on high-temperature modifications of trifluorides of Y, Er, Tm, Yb and Lu, with a structure of the α-YF3 type. © 1979 Akadémiai Kiadó.
