The correct answer is Mica.. Mica is a goodconductorof heat but had a bad conductorof electricity.; Mica has good thermal conductivity due to phonons but doesn't have sufficient free electrons to be a goodconductorof electricity.; The important micas are muscovite and phlogopite, which are used in a variety of applications.; Mica's value is based on several of its unique physical properties.

Glass, for instance, is a very good insulator at room temperature, but becomes a conductor when heated to a very high temperature. Gases such as air, normally insulating materials, also become conductive if heated to very high temperatures. Most metals become poorer conductors when heated, and better conductors when cooled.
