# Opposite of Cryogenics

Cryogenics is related to very low temperatures, so, what is the term when referring to very high temperatures?

There is always amplituaestus. Almost meaning "greatest heat" or "A greatness of heat" really hard to do literal translations with Latin –  Argus May 22 '12 at 3:29
There is no term, because there is no real field of study here. At high temperatures everything becomes uniform gas. Low temperatures are much more interesting than high temperatures. You should think in terms of $\beta$--- large $\beta$ is a wide open field, and low $\beta$ is just one point. –  Ron Maimon May 22 '12 at 3:30

Plasma physics. Sufficiently high temperatures will turn any material into a plasma (decomposing any molecules in the process).

To give MSalter's answer a "ics" word you say "magnetohydrodynamics".

However, I don't think the parallel is perfect. One can say that you have a cryogenic gas system or a where you simply mean "very cold" or cyrogenic hydrogen target (if you're a particle physicist, say) where you mean "cold enough to be liquid", but there doesn't seem to be latin word for "very hot": we have "high temperature ceramics".

"Thermogenic" would seem to be the obvious parallel construction, but it's taken.
