5500C? i thought it's not that much, chemistry can get you there

apparently not

thermite tops at some 2000C-something, and in any case can't work above boiling point of aluminum (2470C)

only in few cases of adiabatic flame temperatures reach above 4000C, and all in oxygen. highest listed in wikipedia is oxygen/dicyanoacetylene at 4990C. maybe some wacky highly fluorinated oxidizer will allow for even higher temperatures. adiabatic detonation temperatures also top out at some 4500C even for the most energetic explosives

so really only practical way to get to 5500C is through use of electric arc

What if we pre-heat the room to 3000, then very quickly introduce the explosives and run away before detonation?

if there's no room left after measurement, did it really happen?

5 trillion K is a lot more than 5500 C.

He's talking about the surface of the sun

Oh, in the picture. I haven't realised it's a part of the parent comment, only read the text.

Makes way more sense then.

Surely a laser would be way more practical

[-] skillissuer@discuss.tchncs.de 7 points 8 months ago

depends on what do you want to heat up. hint: at 5500C you need to handle plasma anyway

You're only off by about 9 zeros.
