This Nanografi germanium (Ge) micron powder is a high-purity elemental material supplied at 99.99 % purity with a particle size of 100 mesh. Identified by CAS number 7440-56-4, it is intended for laboratories and developers working in electronics, optoelectronics and semiconductors.
Germanium crystallises in a diamond structure and has a density of 5.32 g/cm³. The material melts at 937.4 °C and boils at 2830 °C, with an electric resistivity of 47 x 10 ⁻⁶ microhm-cm and a coefficient of expansion of 6.1 x 10 ⁻⁸ at 20ºC.
The powder is offered in 25gr, 100gr, 500gr and 1000gr packs, so it suits both small-scale trials and larger batches.
- Research and development of electronic materials and components.
- Optoelectronics work where germanium is used as a functional material.
- Semiconductor studies requiring high-purity germanium powder.
