General description
Germanium(IV) oxide (GeO₂) is a semiconductor material known for its notable optical properties and high refractive index. It finds extensive use in various applications within electronics and optics. This compound is slightly soluble in water and acts as a catalyst in industrial processes. Additionally, GeO₂ is employed in the development of sensors for gas detection and other chemical species, utilizing its semiconductor characteristics to enhance sensitivity and response times.
Application
Germanium(IV) oxide can be used:
- To prepare glasses for nuclear radiation shielding and ultra-broadband amplification. For example, germanium and bismuth oxide glasses.
- As a precursor to synthesize GeO2/TiO2 nanocomposites that can be used for the photocatalysis of organic pollutants.
- As an anode material for lithium-ion batteries due to its high lithium storage capacity, thermostability, and large volume expansion during the charge–discharge process.
