Property+and+Uses+of+Selenium

__//Selenium is used in foods, it is used in some solar panels, and in some factories to control electricity.

Selenium is used in foods because it helps the bodies immune system. Selenium is in many everyday foods we consume without even thinking. Selenium is in nuts and most fish. Selenium is made as vitamins and is used as a key ingredient in certain diet supplements. Selenium can help fight off sicknesses and therefore it is good for a human body.

Selenium is used in some Solar panels because it has a unique property with electricity. Selenium is a non metalic conductor. Selenium conducts electricty depending on how much light is shone upon it at one time, so the more the light the more electricity is allowed to flow through it. So to make solar panels cheaper manufacturers have started using selenium instead of expensive wiring to make solar panels.

In factories they are used to help control electrical currents because it sometimes is used in the very wires. Selenium can be put in the wires and so that in the dark the wires cannot function but when out into the light they function quite well. This prevents wires that in the dark and may be exposed to other elements to not work and not allow electricity to them so that disasters do not occur.
