  • Applications

    Calcium iodate is used primarily as a source of iodine for salt iodization in the food industry, offering stability in humid conditions; it also serves as an iodine supplement in animal feeds and in certain pharmaceutical or dietary supplement formulations. In industrial manufacturing, calcium iodate may be employed as an oxidizing reagent or iodine source in specialized chemical synthesis and processing steps.
