The study of borazine has been limited due to the cost of raw materials and the reaction apparatus in addition to the low yield less than 30%. Pure borazine has been synthesity by using inexpensive raw materials(NaBH₄ and (NH₄)₂SO₄) and simple glass reaction apparatus with much improved yield over 50%. The synthesized borazine and its polymerized product are characterized by IR, ¹H-NMR and TGA/DSC, then compared to commercial products. It was, finally, confirmed that the borazine polymer was converted to a pure boron nitride(h-BN) on heating to 1500℃ with 75% ceramic yield.
