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 Ttr than those closest to stoichiometry, i.e., where the I2 Hg ratio is 2.000.
