Mn4 Si4 O14

Mn₄Si₄O₁₄ is a mixed-valence manganese silicate ceramic compound that functions as a semiconductor material, combining manganese and silicon oxide phases into a single crystalline lattice. This material belongs to the family of transition-metal silicates and is primarily of research and developmental interest for applications requiring both ionic and electronic conduction. It is notable for potential use in electrochemical devices and solid-state applications where the coupled manganese oxidation states and silicate framework provide tunable electronic properties distinct from simple binary oxides.
