Germanium tetrafluoride (GeF₄) is an inorganic ceramic compound combining germanium and fluorine, belonging to the halide ceramic family. While primarily of research and specialized industrial interest rather than mainstream engineering use, GeF₄ appears in optical applications, fluoride glass precursors, and semiconductor processing due to germanium's optical transparency in the infrared spectrum and fluorine's chemical stability. Its primary appeal lies in niche optoelectronic and materials chemistry contexts where halide ceramics offer advantages unavailable from silicate or oxide alternatives, though practical applications remain limited compared to more established ceramic families.
