WebThe melting point of graphite is approximately 3,400 degrees Celsius (6,152 degrees Fahrenheit). Graphite is a form of carbon that has a layered structure, with each layer … 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. daryl frazetti be the astronaut https://ryangriffithmusic.com
