· JVASP-10682· Cd2As2O7

Cadmium arsenate oxide (Cd₂As₂O₇) is an inorganic ceramic compound belonging to the family of metal arsenate oxides. This is primarily a research and specialty material used in limited industrial applications rather than a commodity ceramic. The compound is notable in optoelectronic research, particularly for potential use in semiconductor applications and photonic devices, though its toxicity due to cadmium content significantly restricts its deployment compared to safer alternatives in most commercial settings.
