Zirconium tetrachloride (zirconium and hafnium tetrachloride production - from zircon)

The activity generating the emissions is zirconium and hafnium tetrachloride production, from zircon. The reference product is zirconium tetrachloride. Nuclear-grade (hafnium-free) Zirconium tetrachloride (Zirconium (IV) chloride – ZrCl4) is an inorganic compound which serves as an intermediate product for the production of other compounds of Zirconium. Its most prominent use is during the production of pure zirconium metal through the Kroll process. Other applications include: usage as a weak Lewis acid for the Friedel-Crafts reaction, the Diels-Alder reaction and intramolecular cyclisation reactions, and usage in water-repellent treatment of textiles and other fibrous materials. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
