(materials)
A material that is a poor conductor of heat, sound, or electricity.
(solid-state physics)
A substance in which the normal energy band is full and is separated from the first excitation band by a forbidden band that can be penetrated only by an electron having an energy of several electronvolts, sufficient to disrupt the substance.
