Lithium iodate

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] 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.

E.g. water Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazards (white): no code
