Lithium iodate

Lithium iodate (LiIO₃) is a negative uniaxial crystal for nonlinear, acousto-optical and piezoelectric applications. It has been utilized for 347 nm ruby lasers.

Properties

Mohs hardness of lithium iodate is 3.5–4. Its linear thermal expansion coefficient at is 2.8·10^{−5}/°C (a-axis) and 4.8·10^{−5}/°C (c-axis). Its transition to β-form begin at and it is irreversible.
