'''Calcium iodate''' is any of two ]s with the formula Ca(IO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>x</sub>, where x = 0 or 1.

==Production and uses== |
|
|
Lautarite, described as ''the'' most important mineral source of iodine, is mined in the ].<ref name=Ullmann/> Processing of the ore entails reduction of its aqueous extracts with ] to give ]. This ] is a major source of the sodium iodide.<ref name=Ullmann/> |
|
|
|
|
|
Calcium iodate can be produced by the anodic oxidation of ] or by passing ] into a hot solution of lime in which ] has been dissolved. |
|
|
|
|
|
Calcium iodate is used as an iodine supplement in ].<ref name=Ullmann/> ] (EDDI) is a more typical source of nutritional ]. |
