ABSTRACT:
A series of chemically synthesized compounds known as metal mercury iodides or metal tetraiodomercurates having use as infrared detectors are made by reacting potassium tetraiodomercurate(II) with monovalent metal nitrates or iodides, such as thallium(I), indium(I) or copper(I) nitrates. In the case of gold, the gold(I) iodide is used because the nitrate is not known. The precipitated metal (thallium, indium, copper, gold, etc.) tetraiodomercurate is then filtered, dried, and purified (recrystallized) and pressed into a disk under high pressure. Alternatively, the material can be grown as a large crystal by zone melt fusion methods.
