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. Websublimation point [ ‚səb·lə′mā·shən ¦pȯint] (thermodynamics) The temperature at which the vapor pressure of the solid phase of a compound is equal to the total pressure of the gas phase in contact with it; analogous to the boiling point of a liquid.
