Lithium Iodide manufacturers Lithium iodide (LiI) is a chemical compound consisting of lithium and iodine. It is a white crystalline solid that is highly soluble in water and other polar solvents. Lithium iodide has several applications in various fields. In the nuclear industry, it is used as a moderator and coolant in nuclear reactors. It is also used as a component of heat exchange salts in some types of molten salt reactors. In the pharmaceutical industry, lithium iodide is used as a reagent in the synthesis of certain compounds. It is also used as an electrolyte in some types of lithium-ion batteries. Lithium iodide is also used in the production of organic semiconductors and in the manufacture of optical lenses and prisms. It is also used as a dehumidifying agent in air conditioning systems and as an additive in some types of toothpaste and mouthwash. Lithium iodide can be prepared by reacting lithium hydroxide or lithium carbonate with hydroiodic acid. It can also be prepared by the reaction of lithium metal with iodine vapor. Lithium iodide is considered to be a hazardous material and must be handled with care. It can cause irritation to the eyes, skin, and respiratory system upon exposure.
