Why do diamonds sublime

Why would you do that to a perfectly nice diamond? Diamonds need high temperature and pressure degrees at , PSI to gain the atom arrangement that makes them diamonds. Caspar commented on 14 Mar :.

It is used in pencils, and as a lubricant. This conductivity makes graphite useful as electrodes for electrolysis.

However, graphite still has a very high melting and boiling point because the strong covalent bonds that hold the carbon atoms together in the layers require a lot of heat energy to break. Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. Oxidation describes a chemical reaction in which oxygen interacts with other substances. Oxygen is a major part of our atmosphere , and substances oxidize all around us, all the time.

Rust , for instance, is an example of the oxidation of iron. Rust is also known as iron oxide. Diamonds are a form of pure carbon. As carbon oxidizes, the chemical reaction forms the everyday gas es carbon dioxide and carbon monoxide. These are the vapors that a diamond becomes at such high temperatures. In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite.
