Sodium Metagermanate Description
Sodium Metagermanate (Na₂GeO₃, CAS No. 12025-19-3) is a white crystalline inorganic compound composed of sodium and germanium oxide. It serves as a key precursor for germanium-based materials, particularly in the production of germanium dioxide (GeO₂) for optical fibers, infrared optics, and specialty glass formulations. The compound is also used in catalysts, ceramics, and as a corrosion inhibitor in cooling water systems. Its water-soluble nature and reactivity make it valuable in chemical synthesis and industrial applications requiring controlled germanium release.
