Zinc iodide supplier Distributor Manufacturer in chennai Taminadu india

 Zinc iodide is a chemical compound of zinc and iodine,. The anhydrous form is white and readily absorbs water from the atmosphere. It can be prepared by the direct reaction of zinc and iodine in refluxing ether. or by reacting zinc with iodine in aqueous solution:

The structure of crystalline ZnI2 is unusual, and while zinc atoms are tetrahedrally coordinated, as in ZnCl2, groups of four of these tetrahedra share three vertices to form “super-tetrahedra” of composition {Zn4I10}, which are linked by their vertices to form a three-dimensional structure.

Applications

Zinc iodide is often used as an x-ray opaque penetrant in industrial radiography to improve the contrast between the damage and intact composite.United States patent 4,109,065  describes a rechargeable aqueous zinc-halogen cell which includes an aqueous electrolytic solution containing a zinc salt selected from the class consisting of zinc bromide, zinc iodide, and mixtures thereof, in both positive and negative electrode compartments.

In conjunction with osmium tetroxide, ZnI2 is used as a stain in electron microscopy.
