What is germanium used in everyday life?
In addition to its applications in electronic devices, germanium is used as a component of alloys and in phosphors for fluorescent lamps. Because germanium is transparent to infrared radiation, it is employed in equipment used for detecting and measuring such radiation, such as windows and lenses.

What are two interesting facts about germanium?
Interesting Facts about Germanium
- Scientists are studying germanium for use in chemotherapy to help treat cancer.
- Dmitri Mendeleev first named the element “ekasilicon”, but it was later renamed by Winkler.
- Some compounds that include germanium are useful in killing bacteria while not harming animals.
Why is silicon and germanium important?
Silicon-germanium is an important material that is used for the fabrication of SiGe heterojunction bipolar transistors and strained Si metal-oxide-semiconductor (MOS) transistors for advanced complementary metal-oxide-semiconductor (CMOS) and BiCMOS (bipolar CMOS) technologies.
What are 3 common uses of germanium?
The most common use of germanium is as a semiconductor. Germanium is used in transistors and in integrated circuits. It is used as an alloying agent and as a catalyst. It is also used in infrared spectroscopes and infrared detectors.
How is germanium used in phones?
Germanium tetrachloride is used as a dopant – or additive – to increase the refractive index in the silica glass core of fiber-optic lines. Despite its failure as a transistor in the 1950s, germanium is now used in tandem with silicon in transistor components for some cell phones and wireless devices.
Is germanium rare or common?
Germanium is quite rare and found in the Earth at about 1.6 parts per million. The highest concentration has been found in coal seams. 5. Approximately 118 tons of germanium are produced annually and as it is recyclable, some of this is from reclaimed sources.
Why do we use germanium in semiconductors?
Silicon and germanium are used here effectively because they have 4 valence electrons in their outermost shell, which gives them the ability to gain or lose electrons equally at the same time.
Why was germanium used in early transistors?
Germanium played an essential role in the development of the first transistor and its usefulness as a semiconductor thus became recognized. The superior electron and hole mobility of germanium as well as its low melting point has spurred much research into replacing current silicon based devices with germanium.
What are two common uses of germanium?
The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps.
Is germanium still used in semiconductors?
Elemental germanium is used as a semiconductor in transistors and various other electronic devices. Historically, the first decade of semiconductor electronics was based entirely on germanium….
| Germanium | |
|---|---|
| Atomic number (Z) | 32 |
| Group | group 14 (carbon group) |
| Period | period 4 |
| Block | p-block |
How does germanium effect the environment?
Environmental effects of Germanium Physical dangers: The gas is heavier than air and may travel along the ground; distant ignition possible. As a heavy metal it is considered to have some negative impact in aquatic ecosystems.
What are the side effects of germanium?
Side effects of germanium include: Kidney damage. Anemia. Appetite loss. Nerve problems/damage. Muscle weakness/damage. Death.
What uses is there for germanium?
Germanium is used as a semiconductor material.
What are the benefits of germanium?
Uses and Benefits of Germanium Germanium helps in improving body system function and for boosting the immune system. Germanium is also useful for a variety of problems including low energy and eye problems. It also helps in the diseases like AIDS, cancer, heart disease and arthritis.
