Cu4As2O9
ceramic· Cu4As2O9
Cu4As2O9 is a copper arsenate ceramic compound belonging to the family of mixed-valence metal oxide ceramics. This material is primarily of research and specialized industrial interest, used in contexts where copper and arsenic oxides provide specific electrical, optical, or catalytic properties that cannot be easily substituted by more common ceramics. Applications are limited and often experimental, including potential use in electronic ceramics, pigments, or catalytic systems where the unique copper–arsenic oxide chemistry offers advantages over conventional alternatives.
