Can graphene melt
WebContents. I think it has something to do with each carbon atom in Graphene having a delocalized electron and this creates carbon ions that can exert an electrostatic attraction. This would reduce the inter-particle distances between carbon atoms in Graphene relative to Diamond, hence Graphene’s higher melting point. WebCarbon has the highest melting point of all the elements. Previous studies had predicted that graphene – the most thermally stable form of carbon – could melt at 4510K, 1 but new work from Eric Ganz at the Minnesota …
