Preparation
Sodium germanate can be prepared by the fusion of germanium oxide with sodium oxide at high temperatures.
Structure
Na2GeO3 contains polymeric GeO32− anions made up of vertex sharing {GeO4} tetrahedra.[2]
Uses
Sodium germanate is primarily used for the synthesis of other germanium compounds.
gollark: Nope.
gollark: Of course they would do horrible accursed C things. That is the point of C.
gollark: You're obviously saying that to distract us from how you wrote it.
gollark: Unless you wrote it, of course, which you did.
gollark: Done!
