Abstract

The occurrence of deviations from stoichiometry of the semi-insulator compound HgI₂ has been established using a very elaborate chemical analytical procedure. It was found that the molar ratio of I₂ Hg varies from 1.993 to 2.015 (±0.002). The deviations from stoichiometry have been corroborated by studying the red to yellow solid state phase transformation temperature. It was found that the compounds, whether rich or poor in iodine, have lower T_tr than those closest to stoichiometry, i.e., where the I₂ Hg ratio is 2.000.
