Even though the cast iron itself is a poor heat conductor, the oil makes the pan effective when it is at a high temperature.

In electronics, beryllium is used as a p-type dopant in some semiconductors, and beryllium oxide is used as a high-strength electrical insulator and heat conductor.
13.
In earlier times, uranium dioxide was also used as heat conductor for current limitation ( URDOX-resistor ), which was the first use of its semiconductor properties.
14.
The cooking surface is made of a glass-ceramic material which is a poor heat conductor, so only a little heat is lost through the bottom of the pot.
15.
:: : Aluminum foil ( which this pan basically is ) is a sucky heat conductor, especially given that its direct contact area with the stove is probably pretty small.
16.
Although a better heat conductor, an aluminium cylinder head requires steel valve seat inserts, where a cast iron cylinder head would often have employed integral valve seats in the past.
17.
Parker showed in 1958 that even though the Sun's corona is strongly attracted by solar gravity, it is such a good heat conductor that it is still very hot at large distances.
18.
However to make a practical experiment the thermal isolation must be very good because ice itself is a poor heat conductor and will tend to float a long time on slightly warmer water.
19.
But when only thermal equilibrium is considered and time is not urgent, so that the conductivity of the material does not matter too much, one suitable heat conductor is as good as another.

Two truths about sleeping out of doors : Women tend to get colder than men, and mummy bags _ which make their occupants look and feel like a museum exhibit _ are effective heat conductors.
