GeO₃ (germanium trioxide) is an inorganic ceramic compound composed of germanium and oxygen, belonging to the metal oxide ceramic family. While not widely commercialized as a bulk engineering material, germanium oxides are studied primarily in optics, semiconductors, and materials research for their refractive properties and potential in infrared applications. GeO₃ is of particular interest in optical glass formulations, fiber optics research, and as a precursor material in advanced ceramic processing, where its thermal and optical characteristics offer advantages in specialized environments where conventional silicate ceramics have limitations.
