isolator

Non-conductors are materials in which the atomic structure has no free electrons. They have no or only low conductivity

.All electrons of the valence bands are firmly connected with electrons of other atoms and are not available for current transport. Accordingly, the band gap between valence and conduction band is very large. It is over 3 eV and can only be overcome with a large amount of energy. Since non-conductors cannot transport current, they are used as dielectric

for insulation.

Classification of conductors, supraconductors, semiconductors and nonconductors Non

conductors are many inorganic materials such as plastic materials, but also rubber, stone, ceramics, glass and quartz, but also liquids such as distilled water or oil. The resistivity (Rho) of non-conductors is between 10exp3 and 10exp12.
