· JVASP-88857· Mg2GeO4

Mg₂GeO₄ is an inorganic ceramic compound combining magnesium oxide with germanium oxide, belonging to the family of ternary oxide ceramics. While primarily studied in materials research rather than established in high-volume industrial production, this compound is investigated for applications requiring high-temperature stability and chemical inertness, particularly in specialized optics, refractory systems, and semiconductor-related applications where germanate ceramics offer unique thermal and electronic properties compared to conventional silicate alternatives.
