Why is Silicon Used for Electronic Devices?

Aug 31, 2016· Silicon is used for electronic devices because it is an element with very special properties. One of it’s most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. Silicon’s electrical properties can be modified through a process called doping.

Metallography of cast iron insight | Struers

The term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good castability and machinability, as well as moderate mechanical properties.
