Thermal stability of ionic solids: A boiling points survey

Abstract

A survey of those standard inorganic materials which boil without sublimation or decomposition has yielded data for 110 unique materials. These separate according to their ambient lattice energies into groups of monohalides, dihalides, trihalides, tetrahalides and lanthanoid oxides. A wide range of boiling points occurs within each group. The lanthanoid oxides have exceptionally high boiling points which are linearly related to the atomic numbers of their lanthanoid cations through their atomic masses.
