542 Questions
What does germanium smell like?
Germanium itself does not have a distinct odor. It is a metalloid and is typically odorless in its pure form.
What family does element germanium belong to?
Germanium belongs to the carbon family, also known as group 14, in the periodic table. This family also includes elements like carbon, silicon, tin, and lead.
Why did this heresy pose a problem between Germanium tribes?
The heresy posed a problem between Germanic tribes because it caused divisions and disagreements among them over religious beliefs. This could lead to conflicts or even wars as tribes sought to assert their own beliefs over others. Differences in religious practices and beliefs could create tensions and hinder unity among the tribes.
What is the pronunciation rebus for germanium?
Sure! The pronunciation rebus for "germanium" is "jer-MAY-nee-uhm."
What is the scientific name for germanium?
Germanium IS the scientific name for an element that is brittle, crystalline, gray-white, and metalloid.
What is the pronunciation rebus of germanium?
The pronunciation rebus of "germanium" is "jur-MAIN-ee-um."
Germanium is a chemical element, not a poem. It is a metalloid commonly used in transistors and semiconductors due to its electrical properties.
What does iron and germanium have in common?
Iron and germanium are both chemical elements on the periodic table. They are both metals and have similar properties such as being solid at room temperature, having high melting and boiling points, and being good conductors of electricity. However, iron is a transition metal and germanium is a metalloid.
Why is germanium used in amplifiers?
For the same reason silicon is, they are both semiconductors and thus can be used to make transistors which can be used to build amplifying circuits.

It isn't any more. Aside from all the other drawbacks to Germanium (more expensive, noisier, less able to handle high voltages), it becomes "intrinsic" at a fairly low temperature. A pure semiconductor material is called intrinsic, it's also called an insulator. If you put the probes of your ohmmeter in a pail of sand - the material all silicon semiconductors start out life as - the meter will sit there and look at you like "now why did you do that?" To make it do its thing you have to "dope" it with boron or arsenic. Once you spice up your silicon (or germanium, in the case of this thread) with dopants, it's called extrinsic material. Well...what happened is Motorola built a bunch of transistorized car radios with germanium components back in the 1950s, and when the weather got hot the radios all quit working...because at slightly elevated temperatures germanium forgets it's doped.
Compare the characteristics of a silicon and germanium diode?
Potential barrier of silicon is 0.7, whereas potential barrier of germanium is 0.3
What are two common uses of germanium?
Germanium Diodes have a lower forward drop voltage (of 0.3V) compared to more common Silicon Diodes (forward voltage of 0.7V).
Germanium diodes are not very common these days and are hard to find but are still used in hobby AM radio receivers as detectors and also in battery circuits connected to Solar panels.
Very common in guitar pedals.

Why don't use germanium in silicon controlled rectifier?
the leakage current of silicon is less when compared with the leakage current of germanium.. hence scr's are made up of silicon than germanium.. hope tis one is useful to u all!- Vignesh.L(engineer, 1st year)
Is germanium conducts electricity?
Germanium is a metal that conducts electricity and germanium crystals can be prepared in a manner allowing them to conduct electrify through their crystal lattice is one direction only, making germanium crystals valuable for use in transistors and rectifiers.
What is made using the metalloids silicon and germanium?
Silicon and germanium are commonly used in semiconductors in electronic devices such as computers and solar cells. They are prized for their ability to conduct electricity under specific conditions, making them crucial components in modern technology.
Germanium is a semiconductor material and does not have the physical properties necessary to bend like a flexible material. However, it can be engineered into thin layers or structures that may have some flexibility, but it is not a material known for its bendability.
Who is Germanium manufactured?
Germanium is not manufactured; its ore is mined then refined into germanium.
What kind of odor does germanium have?
The pure element has no odor as it is a solid and nonvolatile.
Why cut in voltage of silicon is more than that of germanium?
Silicon has a larger band gap energy than germanium, resulting in a higher cut-in voltage for silicon diodes compared to germanium diodes. The larger band gap in silicon means that it requires more energy for electrons to be excited into the conduction band, resulting in a higher cut-in voltage.
Is germanium a rare earth element series?
No, germanium is not a rare earth element. It is a metalloid in group 14 of the periodic table, along with carbon, silicon, and tin. Rare earth elements are a group of elements found in the lanthanide series of the periodic table.
What country is germanium found in?
Germanium is found in various countries around the world, with major producers including China, Russia, and the United States. These countries have significant reserves of germanium-containing ores and produce the majority of the world's germanium supply.
Germanium is primarily extracted from the by-products of zinc ore processing, as well as from coal ash. It can also be found in small quantities in certain minerals like germanite. Once extracted, germanium is purified through a series of chemical processes to produce high-purity germanium for commercial use.
How will differentiate silicon and germanium diode from a group of diodes?
Simple, Use the multi-meter , switch to the diode option then connect the positive wire to the positive of diode n negative to the negative ( +ve wire red, -ve wire black) if the there is a reading of =~0.7V then it is silicon. and if it is =~ 0.3V then it is germanium.
Which best describes a conducting forward-biased germanium diode?
Negitive cathode, positive anode, voltage accross barrier = 0.3V
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages.
An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
What type of diode is proper to used silicon and germanium?
A: They both have redeemable quality. Germanium has lower turn on voltage as compared to silicon however their current capability is not too great and also have a problem leaking with temperature. SO THE USE IS DEPENDENT ON APPLICATIONS
