Formation of multiphased mixed crystals from miscible NaBr, KBr and KCl

Abstract

Multiphased ternary and quaternary mixed crystals were grown by the melt method, for the first time, using the miscible alkali halides, viz. NaBr, KBr and KCl. X-ray powder diffraction measurements indicate the existence of multiple phases. Density and refractive index were measured and the composition was determined. The metal atom contents determined through flame photometric measurements confirm the estimated composition of the crystals grown. The present study indicates the possibility of preparing multiphased ternary and quaternary mixed alkali halide crystals using the miscible NaBr, KBr and KCl as the starting materials.

“…Since it was realized [1] that alkali halide mixed crystals have the potential for important applications in optical, optoelectronic and electronic devices, the interest on understanding their properties has been largely intensified, thus a large body of experimental studies have recently appeared [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. This large amount of experimental data allowed the investigation of the correctness of early theoretical studies [16][17][18][19][20] the basic aim of which was to calculate the physical properties of a mixed system in terms of the corresponding properties of its end members.…”
