But I've read that melting graphite also requires breaking the covalent $ce{C-C}$ bonds rather than just breaking the van der Waals forces between the layers. And for cross-linked polymers, I've read that melting involves breaking only the bonds linking the two polymer chains. So I guess what I want is a precise definition of melting.

Views: 544. The aluminum industry chain mainly consists of four links: bauxite mining, alumina refining, primary aluminum production and aluminum processing. The first is bauxite mining, and then alumina is extracted by dissolving, filtering, acidifying and burning the bauxite, and then electrolytic aluminum is prepared by electrolytic melting.

Melting point of Graphite is 3600 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which ...
