Abstract: | The phase equilibria in the subsolidus part of 14 binary systems of SrF2(Y, Ln)F3 type (Ln—all lanthanides except Pm and Eu) were studied at temperatures over 850°C in equilibrated and quenched specimens by the X-ray analysis method. The oxygen concentration in the specimens before and after the thermal treatment was checked. The crystallographic characteristics of phases formed in the systems i.e. nonstoichiometric phases Sr1?xLnxF2+x with fluorite type structure, phases with fluorite derived type structure, nonstochiometric phases Ln1?ySryF3?y with tysonite (LaF3) type structure are given in this paper. |
