Abstract
Borazine (B3N3H6) as an inorganic analogue of benzene was synthesized by reaction of cheap raw materials (NaBH4 and (NH4)2SO4), and by using simple glass reaction apparatus in a scale up to 20 g per run with highly improved yield over 50%. It appears that synthesis of borazine is competing with formation of poly(aminoborane) as an inorganic analogue of polyethylene. The synthesized borazine and its polymerized product were characterized by comparison with products obtained from a commercial one. Bulk pyrolysis of the borazine polymer to 1500 ℃ produced a pure boron nitride (BN) with 75% ceramic yield, which displayed good oxidation resistance under dry air.
