- 1034 reads
Germanium is the chemical element and it is a member of group 14 and period 4 in the periodic table. Atomic number of silicon is 32 and is indicated by the symbol Ge. Germanium is a lustrous, hard, greyish- white a metalloid. Germanium's abundance in the Earth's crust is approximately 1.6 ppm. Germanium contains 5 natural isotopes and also 19 artificial isotopes created in laboratory. Natural isotopes are 74Ge, 72Ge, 73Ge, 79Ge, 76Ge.
Germanium Element Uses:
- The most common use of germanium is as a semiconductor. And it is also used in thousands of electronic applications.
- Germanium oxide has a high index of refraction and dispersion. This makes it especially useful for wide-angle camera lenses and objective lenses for microscopes.
- It is used as an alloying agent and as a catalyst.
- It is also used infrared spectroscopes
