Sodium germanate (Na₂GeO₃) is a colorless solid chemical compound.^[1]

Preparation

Sodium germanate can be preparted by the fusion of germanium oxide with sodium oxide at high temperatures.

Na₂GeO₃ contains polymeric GeO₃²⁻ anions made up of vertex sharing {GeO₄} tetrahedra.^[2]

Sodium germanate is primarily used for the synthesis of other germanium compounds.
