I know this is a short post containing what I am saying now, but i just have on simple question and do not have any others.

{Except}

What Is the strongest{temperature wise}material out there?

 

Thanks.

Ceramics would be my guess, several metals can also withstand those temps. Carbon can if it's not incontact with oxygen.

Can ceramics withstand high pressures and water vapor?

 

I guess i should have included that.

 

What metals?

 

Thank you.

Most of the transition metals are good with heat, but i think the best wood be platinum.

Any of the valve metals (tantalum, titanium, niobium, tunsten, hafnium, etc.) or platinum group metals (commonly platinum and nickel)

There are better ones, but Alumina Silicate (Mullite) is pretty inert at high temperatures and is pretty cheap too. What do want it for?

bear in mind 600 is easily achievable by a bunsen burner so you should be familiar with things which can handle that temperature. How about a saucepan?

Even Aluminium will stand 600C (not with much leeway) but I doubt it would have any useful srength at that temperature. Steel would be an easy option.

What do you want to do with this stuff?
