摘要: Abstract Crystalline bulks, obtained by the Bridgman technique from a melt that was previously prepared mixing equal molar fractions of salts KBr, KCl and KI were characterized powder single-plate X-ray diffraction. The crystalline bulks are formed composite material consisting highly textured aggregation crystallites two different face-centred-cubic solid solutions with corresponding unit-cell sizes 7.020(2) 6.456(3) A. relative fraction concentrations these in about 0.348 0.652, respectively. From solutions, first is identified as binary KBr(9.7%):KI(90.3%) mixed phase second discussed to be ternary KBr (45.9%):KCl (51.1%):KI (3.0%) phase. lattices most forming composite, no matter they belong to, spatially coherent each other within bulk.
