Abstract

New preceramic polymers-hybrid polyborosilazanes (H-PBSZ) were synthesized and characterized. The ceramization process of H-PBSZ was investigated by TGA, FT-IR, XRD and SEM. The results show that there exist bonds of B-N, Si-N, B-H, N-H, Si-H in the structures of H-PBSZ. With the increase of pyrolysis temperature, the bonds contained H atoms decrease till they disappear. The ultimate product is a mixture comprised of BN and Si3N4 . The loss of weight in the process of pyrolysis mainly occurs between 100℃ and 400℃, and the ceramic yield is about 83wt％. The pyrolytic product is crystallized as the temperature increases. The products pyrolyzed at 800℃ are almost amorphous with mainly spherical particles, while those pyrolyzed at 1600℃ are well crystallized, and h-BN crystal flakes and α-Si3N4 grains can be observed by SEM.

Key words： polyborosilazane; pyrolysis; ceramization; boron nitride
