PHYSICO-CHEMICAL PRINCIPLES OF VACUUM-THERMIC TREATMENT OF LITHIUM
Abstract
The silico-thermic reducti n of lithium oxide and alumino-thermic reduction of lithium aluminate at equilibrium were studied by the outflow method. Functional relationship between isobaric potential and temperature was established or lithium orthosilicate and lithium monoaluminate formation. Standar entropy and enthalpy values were derived for these compounds. The method of continuous weighing was used to study t e kinetics of aluminothermy with respect to lithium aluminate. The time period dominated by the kinetic factor was defined. The limiting stage is probably associated with the resorpti n of gaseous lithi m. The metal produced by vacuum aluminothermy exceeded in purity the electrolytic product. Black electrolytic lithium was refined in a bubble cap column. The effectiveness of this refining method was demonstrated. (Author)
