· K2 Au2 O4

K2Au2O4 is a mixed-valence gold oxide compound containing potassium, representing an unusual ternary oxide in the gold chemistry family. This is primarily a research material studied for its potential electronic and catalytic properties rather than an established commercial engineering material. The compound is of interest in materials chemistry for understanding gold oxide chemistry and potentially for applications in advanced catalysis, photocatalysis, or functional oxide electronics, though industrial adoption remains limited and the material requires further development and characterization.
