Diamond is the prototypical example of a good thermal conductor ( possibly the best thermal conductor known ) but a bad electrical conductor, i . e . an insulator.

One of the best examples would be the mica used as electrical insulator but thermal conductor in the electric irons-Wikicheng 06 : 11, 17 April 2006 ( UTC)

:: : : Actually, per volume is a better thermal conductor than silver and copper, as gold has more mass ( and this is how it's measured.

Metal, however, is a thermal conductor, so spoons will get hot and cool the beverage while wood will not . talk ) 11 : 38, 14 May 2008 ( UTC)

:: : : : Gold is quite a good thermal conductor, however, 6 times better than steel, 50 % better than aluminum, and only 18.5 % worse than copper.

Copper ( 401 W / ( m�K ) at 300 K ) is significantly more expensive than aluminum ( 237 W / ( m�K ) at 300 K ) but is also roughly twice as efficient as a thermal conductor.

Visually discerning a good quality cubic zirconia gem from a diamond is difficult, and most jewellers will have a thermal conductivity tester to identify cubic zirconia by its low thermal conductivity ( diamond is a very good thermal conductor ).

Most are gases at room temperature; have relatively low densities; are poor electrical and thermal conductors; have relatively high ionisation energies and electronegativities; form acidic oxides; and are found naturally in uncombined states in large amounts.

:: : : Gold will not serve any purpose other than its ornamental use, Since copper is still a better thermal conductor than Gold . ( & # 9794; ) 09 : 31, 25 September 2006 ( UTC)
