Abstract

KR3F10 (R = Ho, Er; sp. gr. ) crystals have been grown by the vertical directional crystallization. The incongruent melting of these compounds is experimentally established, and the temperatures of the corresponding thermal effects are determined. Narrow regions of homogeneity are found for the studied crystals; these regions are also characteristic of the entire series of KR3F10 crystals under study. The cubic lattice parameter monotonically decreases along the crystal length and varies in the range of 11.5782(2)–11.5654(5) Å for KHo3F10 and 11.5225(1)–11.5102(4) Å for KEr3F10. The conditions for growing KR3F10 crystals of optical quality from melt are optimized.
