Ytterbium oxide (rare earth oxides production - from rare earth carbonate concentrate)

The activity generating the emissions is rare earth oxides production, from rare earth carbonate concentrate. The reference product is ytterbium oxide. Ytterbium is a lanthanide, a rare earth element, that is predominatly obtained from the ion adsorption clays of southern China - representing approximately 98% of world production. Ytterbium oxide (Yb2O3) is used in a number of different applications, including as a radiation source in portable x-ray machines, as an alloy in metallurgy, as a dopant of active media and in high stability atomic clocks. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
