Chemical compound

Lithium iodate (LiIO₃) is a negative uniaxial crystal^[1] for nonlinear, acousto-optical and piezoelectric applications. It has been utilized for 347 nm ruby lasers.^[9]^[10]

Properties

Mohs hardness of lithium iodate is 3.5–4. Its linear thermal expansion coefficient at 298 K (25 °C; 77 °F) is 2.8·10⁻⁵/°C (a-axis) and 4.8·10⁻⁵/°C (c-axis).^[1] Its transition to β-form begin at 50 °C (122 °F) and it is irreversible.^[5]
