Smilarities:
Boron Nitride (BN) and Graphite have Hexagonal lattice structure.
The Heteroatomic B-N C6 coefficient is very similar to the C-C coefficient resulting in very similar dispersive contribution to the interlayer binding
The overall binding energies curves of both the materials are very similar.
Differences:
BN is Heteratomic and Grpahite is Homoatomic
Unlike Graphite , BN is a good electrical insulator
High lubiricity of BN doesnot require water or gas molecules trapped between the layers.
Add Answer to:
S. Give at leas three similaritie and threfboron nitride (BN) and graphite.
