Therefore, a more efficient way might be to first heat the diamond up to a very high temperature with a torch or something and then drop it into some liquid oxygen , as seen in the video above. The idea of a molten diamond may seem quite odd as you probably have never seen or even heard of it. This is because the conditions for melting diamonds are so extreme and also very rare. So, there is definitely an argument to be made for whether a molten diamond is even a diamond anymore or just simply liquid carbon.
The above picture is the phase diagram of carbon , which describes the specific forms phases of carbon and the general forming conditions for these phases. From this diagram, we can pick out the conditions for when a diamond crosses over to the liquid phase i.
The interesting thing about these conditions is that a diamond can not actually melt at normal atmospheric pressure levels, so to do it would definitely require a laboratory of some sorts.
This is also where the problem of melting a diamond occurs. See, the diamond would turn into graphite way before it actually reaches the melting conditions when heated in the absence of oxygen as explained earlier. On the other hand, if oxygen is present, the diamond would just burn away before melting.
This is why a high pressure is required as diamond actually becomes a more stable form than graphite in high pressure conditions.
Therefore, the diamond would not turn into graphite before melting, given of course that the pressure is sufficiently high. Researchers were investigating how the diamond reacted to a range of extreme pressures to see if it could be used to encase BB-sized fuel pellets needed to drive a nuclear fusion reaction. Nuclear fusion occurs when multiple nuclei combine to make one heavier nucleus.
Shop Holiday NEW! But I want to see Liquid Diamonds! So do scientists, which is why they developed a way to get around this.
The Largest Faceted Gemstone in History. It involves coating the crystal with a layer of graphene, which is a one-atom thick substance composed of pure carbon. When the coated crystal is heated to high temperatures in order to bond the two substances, a restructuring and bonding between the two elements can be observed.
Since both substances are impermeable, the water trapped between them transform into a supercritical phase, that can corrode the surface of the diamond. As you can see, to destroy a diamond you need special conditions, time and efforts. Am kidding. As for me it is much better to see them shining. This is it. I hope you found this article interesting and useful.
