Thermodynamic optimization of the Cd–Na and Cd–Tl binary systems

“…Predel [17] measured the constitution diagram of the Cd-Tl system by thermal analysis over the whole composition range. The final results were in good agreement with those reported by Kurnakow and Puchin [16]. In addition to the phase equilibrium measurements, the author also presented the activities of Cd and Tl at 603 K in the liquid phase.…”

“…Kurnakow and Puchin [16] carefully determined the liquidus curve in the Cd-Tl binary system by thermal analysis, where 42 melts were used with the concentration ranging from pure Cd to pure Tl. The liquidus curve shows a flattened geometry near the Cd edge, indicating the presence of a metastable liquid miscibility gap and relatively large repulsive forces between Cd and Tl atoms in the liquid phase.…”

Synthesis of the Tetragonal Phase of Zintl’s NaTl and Its Structure Determination from Powder Diffraction Data

“…While it has been known for a century, that the compound KTl exists [13], but does not crystallize in the NaTl structure [14], only in 1993, Corbett et al reported on the crystal structure of the second binary alkali metal thallide KTl [15]. In contrast to the compound containing the lighter homologue sodium, thallium does not form a diamond lattice, rather isolated Tl 6 6− ions [15].…”

125 Years Eduard Zintl

“…Zintl raised this idea in his paper on the determination of the NaTl structure. [1] The existence of NaTl had been deduced before from melt diagrams, [2] and was finally synthesized by Zintl from liquid ammonia solutions of sodium and thallium iodide. [3] Laves' contribution published after Zintl's early death in 1942 put the idea to front by comparing the two AB compounds CsCl and NaTl (Figure 1).…”
