If carbon has the highest melting point of any of our known elements , then how do they melt it , the only thing I could think of is containing it in a magnetic field and maybe using like an electric arc furnace.
cragar said:ok i could see that , how do we keep oxygen away from it so it doesn't burn.
alxm said:You do it in an oxygen-free environment? That's a pretty easy part.
Of course you know that carbon doesn't melt at standard pressure, it sublimates.cragar said:I was just thinking about it one day , thanks for the answer.

Borek said:Agreed. Vacuum or inert gas. Both used in commercial applications on the large scale, so no problems with implementation.
DrDu said:Would there be really be a difference between vacuum and inert gas atmosphere as far as subliming vs. melting? The relevant pressure seems to me to be the partial pressure of carbon and not that of an inert gas.
Carbon can be melted through the process of heating it to a high temperature. The melting point of carbon is very high, at around 3,500 degrees Celsius. This can be achieved by using a furnace or other high-temperature heating equipment.
When carbon is melted, it transforms from a solid state to a liquid state. This means that the bonds between carbon atoms are broken, allowing the molecules to move more freely. The liquid carbon can then be used for various purposes such as casting or forging.
Melting carbon is important because it allows us to manipulate and shape the material into different forms. This is useful in various industries such as metallurgy, where melted carbon is used to produce steel, and in electronics, where melted carbon is used to create semiconductors.
No, carbon cannot be melted at room temperature. As mentioned earlier, the melting point of carbon is very high and requires extremely high temperatures to melt. However, it is possible to transform carbon into a liquid form at room temperature through the process of sublimation, where solid carbon is heated and vaporized.
Some common methods used to melt carbon include electric arc furnaces, induction furnaces, and open-hearth furnaces. These methods involve using high temperatures to heat the carbon and melt it into a liquid form. Other techniques, such as laser melting and electron beam melting, are also used in more specialized applications.
