Physical Properties
Lithium iodate forms colorless hygroscopic crystals of hexagonal syngony , space group P 6 3 2 , cell parameters a = 0.5469 nm, c = 0.5155 nm, Z = 2.
At 255 ° С, a transition to the tetragonal syngony phase occurs, the cell parameters a = 0.973 nm, c = 0.615 nm [1] .
When growing crystals from aqueous solutions at 75 ° C, monoclinic syngony crystals are formed, space group P 2 / n , cell parameters a = 0.9722 nm, b = 0.9725 nm, c = 0.61517 nm, β = 90.01 ° [2] .
It is well dissolved in water.
Application
Lithium iodate forms uniaxial nonlinear optical crystals with high coefficients of nonlinear optical effects in a wide transparency range. It is used in laser systems of low and medium power levels.
