ABSTRACT:
Chemically pure mercuric iodide is purified to form detector-grade mercuric iodide and mercuric iodide semi-conductor crystals by vaporization in an inert gas stream containing deliberate addition of oxygen and iodine vapor and crystallizing the vaporized mercuric iodide in order to remove undesired metallic iodides and organic residues, followed by the elimination of undesired oxides of mercury by the revaporization in a second inert gas stream in the presence of reducing vapors such as carbon monoxide, hydrogen iodide or iodine and recrystallization to produce detector-grade mercuric iodide, and crystal growth in such a reducing atmosphere produces semi-conductor crystals.
