like the rocks they use for building rockets. i heard that they can withstand up to 15000 degrees celcius but i forgot the name.

Graphite can withstand up to about 3650 degrees Celsius. Though it begins to evaporate (sublimate) at less than 3500 C.
I know of no other naturally occurring material that is more heat resistant.
Impure graphite may begin to burn at around 1000 C if exposed to air (In most cases graphite can be considered "self-extinguishing.")
Graphite is used for extremely heat resistant items, such as fire bricks, crucibles, electrodes in electric furnaces used for making steel and aluminum, etc., etc. Graphite reinforced with carbon-fiber cloth is used to make the nose cone and wing leading edges of the space shuttle.

I'm not sure the most heat resistant.
I do know the metamorphic rock that forms under the highest temperature and pressure is ecologite.
Two *extremely* heat resistant minerals are asbestos and kyanite
