This is all a lot of work to make cheap calcium iodide compared to the precursors of iodine and calcium
I would suggest just react them directly in an exothermic reaction just as sodium chloride can be made
I would say calcium hydroxide and iodine could form it but you might just end up with mostly calcium iodate

symboom - I was trying to find ways to make the different iodides in solvents, but indeed for Calcium the direct approach may be tried. Also, Calcium
iodide seems much more expensive here than most other chems I bought, and it is not readily available. Only on backorder. Calcium iodide is of
interest as I wanted to try to then see what happens if I react calcium iodide solution with metal sulphates - whether any would form the metal iodide
in double displacement being that calcium sulphate is not soluble.
Havent tried ether as solvent though, as suggested above...
