Pyrolysis of Polyborazinylamine Precursors of Boron Nitride Ceramics
Abstract:
The pyrolysis of polyborazinylamine precursors leading to boron nitride(BN)ceramics has been studied by means of DTA-TG-GC,FTIR and XRD.The results show that the pyrolysis starts at 180℃ and the loss of 60% weight mainly occurs under 600℃.N2, NH3 and HCl are given off during pyrolysis and h-BN ceramics are obtained at 1600℃.
