Mercuric iodide is a mineral compound with chemical formula HgI2. It is a red-orange solid with very low solubility in water and its crystal structure is tetragonal. It dissolves in alkaline solutions and yields a complex salt.
They affect the chemiluminescence (chemoluminescence) of mercury iodide, which is used in production of high-quality photodetectors, as a catalyst in the transfer of the polymerization group of methacrylates or acrylates, identification of nuclear particles, some metals such as palladium, copper, aluminum, tin, silver, and tantalum.
