· Cr4 O4 F4

Cr₄O₄F₄ is a chromium oxide fluoride compound that functions as a semiconductor material. This mixed-anion ceramic represents an emerging class of materials combining chromium oxide and fluoride phases, primarily explored in research contexts for applications requiring modified electronic or ionic transport properties. The fluoride substitution into the chromium oxide lattice offers potential advantages over conventional oxides, including altered band structures and enhanced ionic mobility in select operating environments.
