· JVASP-50066· Y4Cu2O7

Y4Cu2O7 is a mixed-valence copper-yttrium oxide ceramic compound belonging to the family of rare-earth copper oxides. This material is primarily of research and developmental interest rather than established in high-volume production, with potential applications in functional ceramics where copper-oxygen interactions and rare-earth doping are leveraged for electronic or catalytic properties. Engineers would consider this compound in exploratory projects involving high-temperature ceramics, catalytic substrates, or materials where copper redox chemistry combined with yttrium's thermal stability offers advantages over conventional alternatives.
