[0002] Calcium iodate is a white crystal or powder, odorless and tasteless, with a melting point of up to 540°C (decomposition). It is slightly soluble in water, but insoluble in alcohol solvents, but soluble in nitric acid, showing stable chemical properties. Usually, calcium iodate is prepared by reacting sodium iodate solution with calcium chloride solution.
