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.
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.
Diamond do not melt, it sublimes (solid-gas) at 3642 degrees Celsius.
All objects have melting points but they are high sometimes and low sometimes. There is no object without a melting point.
yes you can melt one but it has to be
If you are a solid, you melt. If you are a liquid, like water, you vaporize.
a diamond's melting point is so highmagma will not melt it
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.
i do not this so :)
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.
The melting point of diamond is sufficiently high that magma would not melt it.
YES about 5000+° more hotter than the maximum of diamond!
Yes you can but it would take a very hot temperature for the diamond to melt. Not any normal hot temperature. Diamond has the highest melting point (3820 degrees Kelvin, or 6416.33 degrees F.)
Diamonds don't melt.
Yes, it would, after all a diamond is just compressed carbon heated up to form a crystal.
diamonds do not melt. when heated to 1800 degrees. diamond, seeing as it is a subsidiary of carbon, turns into gas (CO2)
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.
