graphite melting point bbc bitesize

Why does graphite have a higher melting point than diamond In graphite each carbon atom is linked to three other carbon atoms by covalent bonds In diamond each carbon atom is linked to four other carbon atoms by covalent bonds So it seems paradoxical that diamond would have a lower melting point

Graphite or Copper? Part 1 MoldMaking Technology

01/08/2014Graphite or Copper? Part 1 Copper's low melting point does not allow it to handle current density as effectively as graphite so features on a single copper electrode must be similar in detail graphite is able to achieve near mirror finishes without the use of a powder additive and mirror-like finishes with the additive
