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

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.8. Yttrium is a transition metal that, due its strong similarities, is always found together with lanthranide elements in rare earth minerals. Yttrium is produced through all common rare earth oxide production routes, including carbonate-containing bastnaesite ores, monzonite ores and ion absportion clays. Almost all yttrium oxide (Y2O3) is produced in China. The substance has a number of different applications, including use in fillers, putties, plasters and modelling clay, as well as various medical applications. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
