(Calcium Iodate) 

Calcium iodate: Potassium iodates with a chemical formula Ca (IO3) 2 crystallize in the prismatic monoclinic structure. It is a white color Powder with a very low solubility (3 g / L in 25 ℃) in water, due to the presence of impurities; it can also be colored with pale cream or yellow, which results from anodic oxidation of calcium iodide. The other name is Lautarite, which is commonly used by geologists. This material is the main source of iodine production in Chile.

Most of the calcium iodate is consumed in the country for the preparation of supplements and feed for livestock and poultry, but in other countries it is added to bread pastry, as well as is added to ointments and lotions as disinfectants.
