· JVASP-63076· Yb4As3

Yb4As3 is a rare-earth arsenide ceramic compound combining ytterbium and arsenic in a fixed stoichiometric ratio. This is a research-phase intermetallic ceramic with limited commercial production; it belongs to the family of lanthanide pnictides being explored for thermoelectric, optoelectronic, and magnetic applications where the unique electronic structure of ytterbium can be leveraged. Engineers encounter this material primarily in laboratory and academic settings investigating advanced functional ceramics, rather than in established industrial production.
