Abstract

The Modified Entrainment Method (MEM) was used to compare the vapor pressures of HgI2 from different sources in the temperature range 100-200°C. The vapor pressure varied with the impurity content and the stoichiometry of the materials studied. Impure or nonstoichiometric HgI2 samples were found to have vapor pressures higher than those of purified and more nearly stoichiometric materials. The MEM was used here for the first time to observe a phase transition: red to yellow HgI2.
