Thermal conductivity of graphite
Graphite has excellent thermal conductivity combined with high-temperature resistance. Graphite does not have a melting point; it changes from the solid state directly into the gaseous state. This process is called sublimation. Graphite becomes plastically deformable in an inert gas atmosphere starting at 2500 °C. At temperatures above 3750 °C, Graphite sublimates even without oxygen. Graphite is one of the most chemically resistant materials. It is resistant to almost all media of organic chemi
