Chemistry & industry
Applications
DescriptionCadmium iodide (chemical formula: CdI2) is a chemical compound consisting of cadmium and iodine element. It appears as a green-yellow solid, being soluble in water, alcohol, ether, acetone, ammonia, and acid. It is a compound with the typical crystal structure of the form MX2, exhibiting strong polarization effects. It has many applications such as being used in lithography, photography, electroplating, process engraving, analytical chemistry, electrodeposition of cadium as well as the manufacturing of phosphor and lubricants. It is manufactured through the reaction between cadmium metal, or its oxide, hydroxide or carbonate and hydroiodic acid.
UsesCadmium iodide is used in lithography, photography, electroplating and the manufacturing of phosphors, in engraving process, and was used as an antiseptic and astringent.
UsesUsed in photography, analytical chemistry, manufacturing of phosphors, lubricants
UsesIn electrodeposition of Cd; as nematocide; in manufacture of phosphors; as lubricant; in photoconductors; in photography, process engraving; lithography; in analytical chemistry.
UsesMade by the action of hydriodic acid on cadmium oxide and crystallization. The colorless, flaky crystals are soluble in water, alcohol, and ether. This halide was a common iodizer for collodion formulas, particularly for negatives.
Preparation methods
PreparationCadmium iodide is prepared by the addition of cadmium metal, or its oxide, hydroxide, nitrate or carbonate to hydriodic acid: CdO + 2HI → CdI2 + H2O Also, the compound can be made by heating cadmium with iodine: Cd +I2 → CdI2 A brownish crystalline β-form of the salt may be obtained by slow crystallization from solutions or fused salt mixtures.
