Will a diamond decompose when heated to a high enough heat?

Answer 1

Yes. Diamonds that have been recovered from fires are seen to have decomposed on the surface. They look frosted. The damage does not usually penetrate much into the diamond and the stone can be recut to restore it but it will be a bit smaller.

Answer 2

Diamonds are made from extreme temperatures and pressure deep down within the Earth. Their duress is due to a very rigid structure and organization of the Carbon atoms that compose it.

Putting a diamond at an extreme temperature (we are talking about thousands of Kelvin here) will melt it eventually, or even vaporise it (at an even higher temperature) since the internal kinetic energy transferred from the heating medium will eventually make the the carbon atoms oscillate enough to break their inter-atomic bonds.

Answer 3

It will change it"s state.
Under extreme temperature it will change from the extremely hard diamond to softer carbon,they are both the same thing.
Carbon!

Answer 4

well diamonds will if put into an oven and cooked at a constant temperature (unsure what the temperture is) turn into carbon dust they are not stable as a crystal.

Answer 5

Diamonds can burn but you need an extreme heat like an oxyacetylene torch

Answer 6

Yes, diamond will vaporise in the end, it doesn't melt. If there is oxygen it will also burn and make carbon dioxide.

Answer 7

no. it was the extreme high temperature and pressure beneath the earth that tranformed carbon into diamond.

Answer 8

Yes,and with air or oxygen present, it will burn.

Answer 9

YES
