About Germanium pieces, 1-5 mm, 99.999%

Vaqora Chemicals supplies Germanium pieces, 1-5 mm, a thin-film deposition material registered under CAS number 7440-56-4 at a purity of 99.999%. With the molecular formula Ge, it has a molar mass of 72.63 g/mol. The IUPAC name is germanium. It is also known as Germanium 5N.

In its supplied form it is pieces or chunks. Literature values give a melting point of 937 °C and a density of 5.35 g/mL at 25 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for PVD and sputter coating, thin-film deposition, semiconductor fabrication and electronics and thin films. Buyers come mainly from academic and industrial research and electronics and semiconductors.

We offer Germanium pieces, 1-5 mm in 1 g, 5 g, 100 g and 1 kg packs with a batch-specific COA, and ship to customers worldwide.
