How silicon is made - material, making, history, used

When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.

Introduction to Light Emitting Diodes - Microscope

Introduction to Light Emitting Diodes. In order for a solid to conduct electricity, its resistance must be low enough for electrons to move more or less freely throughout the bulk of the material. In its pure form, silicon does not have sufficient charge carriers, or appropriate band gap structure, to be useful in light emitting diode

Does Silicon Conduct Electricity? | Reference

Does Silicon Conduct Electricity? Silicon is typically a very poor conductor of electricity and often considered an insulator. However, a process called doping introduces a small amount of other material into the crystal structure to convert silicon from an insulator to a semiconductor.

Principles, effects and problems of differential power

The electricity cost of calcium carbide accounted for 66% in Henan province in 2007 which was 12% higher than the average of China and it rose to 71% in 2008 as the differential pricing policy. Therefore the payoffs of enterprises producing calcium carbide are very sensitive to electricity tariff changes.
