Density：3.67 g/cm3
Melting point：661 °C (1,222 °F; 934 K)
Boiling point：1,304 °C (2,379 °F; 1,577 K)
Solubility in water：1587 g/L (0 °C);1842 g/L (25 °C);2278 g/L (50 °C);2940 g/L (70 °C);3020 g/L (100 °C)
Solubility：ethanol, acetone
Band gap：5.89 eV
Magnetic susceptibility (χ)：−57×10−6 cm3/mol
Refractive index (nD)：1.93 (300 nm);1.774 (589 nm);1.71 (10 µm)

Application
Sodium iodide commonly is used to prevent iodine deficiency. Used as analytical reagents, in the manufacture of disinfectants, antiseptics, deodorants and medicines. They are used in baking ingredient conditioner and as animal feed. It is used for conversion of an alkyl chlorides into an alkyl iodides, such as in the treatment of thyroid cancer and hyperthyroidism and in scintillation detectors, traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements.
