Ag. Morachevskii, PHYSICOCHEMICAL, STRUCTURAL, AND TECHNOLOGICAL INVESTIGATION OF LIQUID POTASSIUM-LEAD ALLOYS, Journal of applied chemistry of the USSR, 65(6), 1992, pp. 993-1007
Potassium alloys form a typical system with intensive interaction betw
een the constituents, which results in close ordering in the liquid st
ate and the formation of complex particles characterized by a definite
geometric distribution of atoms. In the present survey the author ana
lyzes the results of investigating the system's phase diagram, thermod
ynamic properties of liquid alloys, and their structural, volumetric,
electrical, and other properties. Using modeling concepts the relation
between thermodynamic functions and concentration is analyzed. The ph
ysicochemical principles of potassium production by electrolysis of ch
loride-carbonate melts with a liquid lead cathode, followed by distill
ation of potassium from the melt, are also discussed.
