The main application of lithium iodide trihydrate

Lithium iodide is a colorless or white cubic crystal system. Easy deliquescence. It is known to have hydrates, halohydrates LiI·1/2H2O, monohydrates LiI·H2O, dihydrates LiI·2H2O, and trihydrates LiI·3H2O. These hydrates are usually stable (the liquid phase composition is the same as the composition of the compound when dissolved, and no decomposition occurs). Commercially available products are usually trihydrate. Lithium iodide (sanshui) : hexagonal crystal system, yellow crystal. The molecular mass is 187.89. Relative density 3.48. Melting point is 73 ℃. [...]
