· JVASP-21783· YbAsO4

YbAsO4 is a rare-earth arsenate ceramic compound combining ytterbium with arsenic and oxygen in a mixed-valence oxide structure. This material belongs to the family of rare-earth phosphate and arsenate ceramics, which are primarily investigated in research settings for specialized optical, nuclear, and high-temperature applications rather than established commercial production. The ytterbium arsenate class shows promise in photonic materials, nuclear waste immobilization, and potentially as host matrices for rare-earth dopants in laser or scintillator systems, though widespread industrial adoption remains limited and material availability is constrained to specialized synthesis.
