How was selenium used in the past?
In the past, selenium was mainly used in the production of glass to remove color caused by impurities and to make glass more transparent. It was also employed in photographic paper to increase sensitivity to light. Additionally, selenium was used in early electronics as a rectifying agent in devices like rectifiers and photovoltaic cells.
What is the use of selenium photocells?
Because of its photovoltaic and photoconductive properties, selenium is used in photocopying, photocells, light meters and solar cells. Its use as a photoconductor in plain-paper copiers once was a leading application but in the 1980s, the photoconductor application declined (although it was still a large end-use) as more and more copiers switched to the use of organic photoconductors. It was once widely used in selenium rectifiers.
How many moles of selenium in selenium tetra-fluoride?
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
Is selenium a nonmetal?
Yes. selenium is a non metal
Who made Selenium?
Jons Jacob was the man to discover Selenium.
Why germanium is not suitable for rectification?
Any semiconductor can be used for rectification, so germanium is suitable.However what you may be thinking of is power rectifiers. Germanium cannot operate with a junction temperature above about 60C, so this is a significant limitation on the power handling capability of germanium power rectifiers (even copper oxide or selenium power rectifiers can handle more power, so they were used for many years before quality silicon power rectifiers became available).

The purpose of 240V to 12V rectifiers?
The purpose of rectifiers is to change AC to DC.
What are the applications of precision rectifiers?
Precision rectifiers are used in the design of instrumentation systems.
Where can rectifiers be bought for a good price?
Maplin offer affordable rectifiers. Rectifiers are used to convert alternating current to direct current. The process is also known as rectification. Rectifiers are often found serving as components of DC power supplies.
What is a polarization rectifier unit?
Chemical Processes often have large power rectifiers as their primary source of DC Power. If these rectifiers are turned off, either for maintenance or a malfunction, there is a danger to the hardware of the chemical process. To solve this problem, standby rectifiers are installed in parallel with the main rectifiers. These rectifiers, known as Polarisation Rectifiers, pass electric current through the process and prevent damage....NEOWATT ENERGY

Is fans used in rectifiers?
no
What is the purpose of rectifiers?
voltage
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
What is the correct name for SeF6?
This compound is called selenium hexafluoride.
How many moles of selenium in selenium tetra-fluoride?
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
