Mineral Gallery: Electrical Properties of Minerals

Most minerals are electrical insulators (10 4+ ohm-meters). A few, mostly metals plus graphite, are conductors. Note that most elements are metals and excellent conductors of electricity, with resistance in the range of 10 -8 ohm-meters. And a few elements are semi-conductors, such as silicon, germanium, and tellurium.
