Yes it is possible. However it is impossible to do at standard temperatures and pressures like that at SATP. It has been done by the Z-Machine at the Sandia National Laboratories by using a pressure of 10 million times normal Atmospheric pressure. To create the pressure, the machine's magnetic fields hurled small plates at the diamond at 34 kilometers per second (21 miles per second), or faster than the Earth orbits the Sun.
Unfortunately in open air, the fact that is it large network of covalently bonded carbons make it extremely hard to melt in the first place. Secondly, diamond at high temperatures will not melt, rather it will prefer to burn, as characteristic of all carbon allotropes. A diamond will burn or oxidize when exposed to a hot flame in the presence of oxygen, for example an oxygen torch with a temperature of 800 degrees C (1,472 degrees F), according to The Merck Index, a standard chemistry reference work.
but it can be melted in the absence of air (or in vacuum) at a very very very high temperature
Since the melting point of diamond, the highest melting point required of any mineral -- 3820 degrees Kelvin -- a melted diamond is uncommon.
Read more about the mineral diamond, below.
Not humanly possible, but if temperatures reach (I will get back to you) it is possible.
It is pressure dependent. A normal atmospheric pressure it sublimates at about 4,330 degrees Celsius.
Yes, but only at extremely high temperatures, something like above 2000 degrees Celsius.
A diamond is a substance that is cold to the touch but cannot melt due to its high melting point of around 4,000 degrees Celsius.
Diamonds do not melt, but they can burn. Diamonds are formed at extremely high pressure and temperatures, but will burn in the presence of oxygen, like an oxygen torch at 1472 degrees Fahrenheit.
Diamonds, rocks, and certain metals such as tungsten do not melt at normal temperatures. Additionally, some ceramics and glasses have very high melting points and can withstand extreme heat without melting.
No, diamond does not have the highest melting point among all materials. Tungsten has the highest melting point of any metal at 3422°C, while carbon sublimes (changes from solid to gas) at around 3915°C without melting.
You as a human cannot melt from heat. The worse thing is that you might get burnt. EXP: An ice cube will melt in heat...I don't think you're an ice cube!! :)
a diamond's melting point is so highmagma will not melt it
The melting point of diamond is sufficiently high that magma would not melt it.
YES about 5000+° more hotter than the maximum of diamond!
The hardest thing to melt is diamond, which requires extremely high temperatures of around 6,000 degrees Fahrenheit to melt.
No, not if the diamond is on earth, and not closer to the sun.
You can melt a diamond, because anything can melt given enough heat. Diamond, however, has the highest melting point of any known mineral: 3820 degrees Kelvin, 6416.33 degrees Fahrenheit, or 3546.85 degrees Celsius.
Diamonds don't melt.
Yes, it is possible to melt a diamond. Diamonds can be melted at extremely high temperatures of around 6,000 degrees Fahrenheit in a controlled environment with the use of specialized equipment such as a high-powered furnace.
Diamonds are the hardest known natural material (from Carbon) and with a melting point of over 3500`c it would be pretty much impossible to melt one down. Only another diamond can scratch a diamond but it wont melt it.
Diamond is difficult to melt because of its strong covalent bonds. These bonds are very strong, requiring a high amount of energy to break them and melt the diamond. Additionally, diamond has a very high melting point of about 3,500 degrees Celsius, further contributing to its difficulty in melting.
The nature of the diamond is such that it is 'worked' or fabricated by cutting and polishing, not by melting and casting, since in order to melt a diamond you'd need to generate heat up to 3,820 degrees Kelvin, or 3,547º C.
Diamonds don't melt, so your question doesn't have an answer.
