Product Application of Potassium iodate CAS#7758-05-6

Potassium iodate is an iodine-containing salt with the chemical formula KIO₃. Compared with potassium iodide, it features superior chemical stability, especially in hot and humid environments. Potassium iodide is hygroscopic and prone to hydrolysis under such conditions, whereas potassium iodate enjoys a longer shelf life. Additionally, it can effectively block the thyroid gland from absorbing radioactive iodine. It occurs as colorless monoclinic crystals or odorless white crystalline powder. It is soluble in water, dilute acids, ethylenediamine, ethanolamine and aqueous potassium iodide solutions; slightly soluble in liquid sulfur dioxide; and insoluble in alcohols and ammonia. With a monoclinic crystal structure and a density of 3.90 g/cm³, it remains stable at room temperature. It melts at about 560 °C with partial decomposition and oxygen release. Its water solubility rises with temperature: moderately soluble in cold water (4.74 g/100 mL at 0 °C) and highly soluble in boiling water (32.3 g/100 mL at 100 °C).
