Zirconium iodate is an inorganic compound with the chemical formula Zr(IO₃)₄. It can be prepared by reacting sodium iodate and zirconium sulfate tetrahydrate in an aqueous solution. The resulting precipitate is dried and refluxed in concentrated nitric acid.^[1] Zirconium iodate trihydrate can be obtained by reacting hydrated zirconium oxide and iodine pentoxide (1.4~3.3% concentration) in water.^[2] Its basic salt Zr(OH)_n(IO₃)_4−n is known.^[3]
