• KDy 3 F 10 crystals have been grown from melt by the Bridgman technique. The incongruent character of melting of this compound is confirmed. The optimal melt composition for growing KDy 3 F 10 crystals has been determined experimentally and found to be 27.0 ± 0.5 mol % KF. KDy 3 F 10 , as well as KTb 3 F 10 , is a phase of variable composition. It is characterized by the presence of a small homogeneity region, where the cubic lattice (sp. gr. ) parameter is limited to the range from 11.6276(2) to 11.6118 (2) Å. The temperature dependence of the thermal conductivity of KDy 3 F 10 and DyF 3 crystals has been investigated for the first time, and some of their optical characteristics have been studied.
