Graphite melting
WebAug 14, 2024 · Due to strong covalent bonding within the layers, graphite has a very high melting point, as expected for a covalent solid (it actually sublimes at about 3915°C). It is also very soft; the layers can easily slide past one another because of … WebGraphite does not have a melting point; it changes from the solid state directly into the gaseous state. This process is called sublimation. In an inert gas atmosphere, graphite becomes plastically deformable starting at a temperature of 2500 °C. At temperatures above 3750 °C graphite sublimates even without the presence of oxygen.
