Zirconium for use in jewelry. Zirconia is a component in some abrasives, such as grinding wheels and sandpaper. A small fraction of the zircon is converted to the metal, which finds various niche applications. Because of zirconium's excellent resistance to corrosion, it is often used as an alloying agent in materials that are exposed to aggressive environments, such as surgical appliances, light filaments, and watch cases. The high reactivity of zirconium with oxygen at high temperatures is exploited in some specialised applications such as explosive primers and as getters in vacuum tubes. The same property is (probably) the purpose of including
Zirconium(IV) iodide Zirconium(IV) iodide Zirconium(IV) iodide is the chemical compound with the formula ZrI. It is the most readily available iodide of zirconium. It is an orange-coloured solid that degrades in the presence of water.The compound was once prominent as an intermediate in the purification of zirconium metal. Like most binary metal halides, it adopts a polymeric structure. As characterized by X-ray crystallography, the compound exists as a polymer consisting of octahedral Zr(IV) centers, each with a pair of terminal iodide ligands and a four doubly bridging iodide ligands. The Zr-I distances of 2.692 (terminal) and 3.030 Å This compound is volatile,
