摘要: Yttrium tends to occur in the same ore deposits as lanthanides and exhibits similar chemical properties rare earth elements. sources are typically concentrated China, there concerns about supply security. is used small, but essential, quantities a variety of advanced industrial sectors, for example, phosphors, ceramics, optical glasses, batteries. In terms resource security, it important verify domestic yttrium consumption trends. order characterize trends Japan, we tracked historical patterns from 2001 2011 by applying bottom-up approach illustrated recent flow using substance analysis. The results showed that total has remained steady over 10 years, 1,124 tonnes (t) 967 t 2011. Recent was driven primarily use fluorescent lamps (462 t), nickel metal hydride batteries (185 optic glasses (149 t). [ABSTRACT FROM AUTHOR]
