The materials science equivalent of a tardis ?
Have a read of the article I linked.
As with lots of things though its a bit of word trickery. If you stuck them in a furnace and heated them up, they'd melt. But a combination of ceramic coating and air cooling keeps them solid and functioning!
A similar situation is during manufacture of steel. Continuous casters use copper moulds (melting point 1000°C) to hold molten steel (c. 1500°C). They don't melt due to conducting powders and lots of water cooling!
