Mg2 Cr8 O18

Mg₂Cr₈O₁₈ is a mixed-valence chromium oxide compound in the semiconductor family, combining magnesium and chromium in a spinel-related crystal structure. This is primarily a research material studied for its electronic and catalytic properties rather than a mature commercial product. It shows promise in photocatalysis, gas sensing, and catalytic applications where the synergistic effects of multiple oxidation states and oxide phases can be exploited, though applications remain largely in the laboratory or early development stage.
