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 tetraiodomercurateII with monovalent metal nitrates or iodides, such as thalliumI, indiumI or copperI nitrates. In the case of gold, the goldI 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. Patents. aw
