thus leading to a flow of electricalcurrent. Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors. Pure elemental silver is one of the best electrical conductors. Other good electrical conductors include the...
Graphite is a good conductor of both heat and electricity. However, in an inert gas or vacuum, graphite is extremely temperature-resistant which makes it an excellent material for high temperature applications. By heating graphite up to 3000掳C its properties are optimised. As a result, heat ...
