Boron nitride synthesis

8synthesis methods

Product Name:Boron nitride
CAS Number:10043-11-5
Molecular formula:BN
Molecular Weight:24.82

Boron nitride is prepared by heating boric oxide with ammonia:
B₂O₃ + 2NH₃ → 2BN + 3H₂O
Alternatively, the compound can be prepared by heating boric oxide or boric acid with ammonium chloride or an alkali metal cyanide. Purified product can be obtained by high temperature reaction of boron halide with ammonia:
BCl₃ + NH₃ → BN + 3HCl
Boron nitride can also be made from the elements by heating boron and nitrogen at red heat.
