Abstract

The system CuCl2-KCl was obtained at room temperature by evaporation of its aqueous solutions, and observations were made on its behaviour at room atmosphere and in an atmosphere poor in water. With the Boetius apparatus, mixtures of CuCl2 and KC1 were observed up to 673 K. The observations explain the unstable character of the solid system CuCl2-KCl during its instrumental analysis in air atmosphere, and also explain the phenomenon of melting of the solid system CuCl2-KCl with molar ratios of Cu to K of from 0.5 to 2.0. Conclusions were drawn on the constitution of the mixtures in the solid state, and also partially in the melt.

Zusammenfassung

Durch Verdampfen wäßriger Lösungen wurden bei Raumtemperatur CuCl2 — KCl Systeme erhalten, deren Verhalten in normaler Raumatmosphäre und in wasserarmer Atmosphäre beobachtet wurde. Mittels eines Boetius Gerätes wurden Mischungen aus CuCl2 und KCl bis zu einer Temperatur von 673 K beobachtet. Die Untersuchungen erklären den unstabilen Charakter des CuCl2 — KCl Feststoffsystemes bei der instrumenteilen Analyse in normaler Luftatmosphäre und erklären auch Die Erscheinung des Schmelzens des CuCl2 — KCl Feststoffsystemes mit einem Cu zu K Molverhältnis von 0,5 zu 2,0. Es wurden Schlußfolgerungen über die Konstitution der Gemische im festen und teilweise auch im geschmolzenen Zustand gezogen.
