Hafnium tetrachloride (market for hafnium tetrachloride)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product hafnium tetrachloride (Hafnium (IV) chloride – HfCl4) is an inorganic compound which serves mostly as a precursor to most hafnium organometallic compounds. It is produced through various processes such as carbochlorination of the zircon sands and then separation of zirconium / hafnium by extractive distillation. HfCl4 is also used i) as a precursor to highly active catalysts for the Ziegler-Natta polymerization of alkenes especially propylene or ii) for other applications in organic synthesis. The cut-off classification is allocatable product. The activity type is market activity. The reference product amount is 1.
