Yttrium is a material that is obtained by refining xenotime in the Ore Refining System. Specifically, xenotime ore can be mined using the Mine Extractor in 15 minutes with level 3 mine software and then refined in 7-8 minutes. Alternatively, a xenotime bracelet can be recycled; this will yield a xenotime gem, which can then be refined to gain yttrium 1-2 minutes. Xenotime ore, gems, and bracelets have a stack limit of 50; yttrium has a limit of 300.
Yttrium is used to produce the following items:
