Diamond.

As we have learnt in our last topic, diamond has a covalent lattice structure.  Each carbon atom is covalently bonded to 4 other carbon atoms to create a 3-dimensional lattice structure.  These primary covalent bonds are very strong, and require a large amount of energy to break them.  Because of this, diamond has both very high melting and boiling points.

So to answer your question Ashleigh, from my research, it seems that the melting point of diamond is around 3600°C while the boiling point is around 4800°C!

You can read more about covalent network structures here.  There are also some little interactive activities where you get to build the structures of diamond and graphite.
