One of my possible products is Lead Nitride (Pb3N2) - from what I can tell, it is not an actual substance; on the contrary, however, there seems to be no evidence I can find disproving it's existence. Boron does not generally make ionic bonds, it forms stable covalent bonds. In this case, since the constituent molecules of graphite are held together by a strong covalent force, a high amount of energy is needed to weaken that bond. Graphite has a melting point similar to that of diamond of around 3600C, at which point it sublimes rather than melting.
