Mercuric Iodide 7774-29-0 - Grade: Reagent Grade

Mercuric Iodide, also known as Mercury(II) Iodide or HgI2, is an inorganic compound that is used as a component in radiation detection devices, such as X-ray film and radiation counters. The compound is formed by combining two elements, mercury and iodine.
Mercuric iodide is a yellow-orange crystalline solid with a molecular weight of 466.62 g/mol. It has a melting point of 535 A C and a boiling point of 1,093 A C. The compound is highly soluble in water and insoluble in alcohol, which makes it useful in various applications.
In radiation detection, mercuric iodide is used as a scintillating crystal. Scintillating crystals produce light when subjected to ionizing radiation, and the light produced can be detected and used to determine the energy and intensity of the radiation. Mercuric iodide is particularly useful in this application due to its high density, which makes it highly sensitive to radiation, and its high atomic number, which makes it able to produce a large amount of light in response to radiation.
