Semiconductors And Optical Coatings Application Cylinder Gas Gef4 Germanium Tetrafluoride

Germanium tetrafluoride, also known as GeF4, is a chemical compound consisting of one germanium atom bonded to four fluorine atoms. It is a colorless gas at room temperature and pressure. Germanium tetrafluoride is highly reactive and is primarily used in the production of optical fibers and as a precursor for the deposition of germanium-containing thin films.

Here are some key properties of germanium tetrafluoride:

Chemical formula: GeF4
Molar mass: 130.53 g/mol
Density: 3.54 g/cm³ (at 25°C)
Melting point: -36.5°C
Boiling point: 4.65°C

Germanium tetrafluoride reacts readily with water and moisture in the air to form hydrofluoric acid and germanium dioxide. It is also corrosive to metals and can react with certain organic compounds. Therefore, it requires careful handling and storage.

In the production of optical fibers, germanium tetrafluoride is used as a dopant to modify the refractive index of the silica glass, allowing for efficient transmission of light signals. It is also employed in the chemical vapor deposition (CVD) process to deposit germanium-containing thin films onto substrates for various applications, including semiconductors and optical coatings.

It's important to note that germanium tetrafluoride is a toxic substance, and exposure to it should be avoided. Proper safety precautions and handling procedures should be followed when working with this compound.
