Characteristic
Mercury(II) iodide is a chemical compound with the molecular formula HgI2. It is typically produced synthetically but can also be found in nature as the extremely rare mineral coccinite.
Chemical formula：HgI2
Molar mass：454.40 g/mol
Appearance：orange-red powder
Odor：odorless
Density：6.36 g/cm3
Melting point：259 °C (498 °F; 532 K)
Boiling point：350 °C (662 °F; 623 K)
Solubility in water：0.006 g/100 mL
Solubility：slightly soluble in alcohol
Magnetic susceptibility (χ)：−128.6·10−6 cm3/mol
Refractive index (nD)：2.455
Crystal structure：Tetrahedral
Application
Mercury(II) iodide is used for preparation of Nessler's reagent, used for detection of presence of ammonia.
Mercury(II) iodide is a semiconductor material, used in some x-ray and gamma ray detection and imaging devices operating at room temperatures.
In veterinary medicine, mercury(II) iodide is used in blister ointments in exostoses, bursal enlargement, etc.
It can appear as a precipitate in many reactions.
