Process for the manufacture of alpha mercuric iodide single crystals and single crystals produced thereby; process for the purification of an alpha mercuric iodide solution

摘要

Process for the preparation of alpha mercuric iodide monocrystals by growth in solution, wherein an alpha mercuric iodide solution in an organic sulphoxide is used and wherein growth is brought about on a nucleus located in a cavity able to block the growth defects of the monocrystal. The invention also relates to the alpha mercuric iodide monocrystals with octahedral-pinacoid habits obtained.
