· JVASP-14621· Yb

Ytterbium (Yb) is a rare-earth lanthanide metal with a body-centered cubic crystal structure at room temperature. It is used primarily in specialized optical, electronic, and nuclear applications where its unique electronic properties and neutron absorption characteristics provide technical advantages. Notable applications include laser materials (particularly in fiber lasers and solid-state lasers), nuclear control rods, and research into advanced alloys where ytterbium's chemical reactivity and rare-earth behavior enable performance improvements over conventional metallic alternatives.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
