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