Starlite would work, good luck finding any though.

Depends on the application.
After cleaning my crystal it tells me you need some ceramic material like aluminum oxide or maybe silicium dioxide.
In the metal department you are basically lost unless you want to pay a fortune AND have legal access to military grade steel alloys but even they will only tolerate this stress short periods of time.

Aluminium oxide is really out, 2000C is very close to its melting point

Silica melts at no more than 1700C

I've designed ultra high temperature furnaces.

No, as I said, 2000 C is very close to the melting point even of the most expensive pure grades of Alumina.

Boron nitride.

Silicon carbide.

There are some other ceramics that can handle it.
