Solvus of KCI:Pb²⁺ Solid Solution from Flotation Measurements of Single Crystal Density

Abstract

The solvus of KCl:Pb2+ is found in the concentration range from 1.6 × 10−2 to 8 × 10−2 mol.% at temperatures ranging from 450 to 250 °C. The decomposition of the solid solution after various regimes of heat treatment is judged by a change in the crystal density determined by the flotation technique.
