· Na2GeO3

Sodium germanate (Na₂GeO₃) is an inorganic oxide ceramic compound belonging to the germanate family of materials. It is primarily investigated in research and specialized applications rather than high-volume industrial use, with potential applications in optical materials, glass formulations, and solid-state electrolytes where germanium's unique electronic properties can be leveraged.
