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.

Material properties of diamond - Wikipedia

Minerals | Encyclopedia

2019-3-31 · Whereas copper is useful because it conducts heat and electricity well, other minerals (e.g., kyanite, and alusite, muscovite, and silimanite) are valuable for their ability not to conduct heat or electricity. Muscovite is often used for insulation in electrical devices, though its many qualities make it a mineral prized for a nuer of reasons.
