以三氯化硼(BCl3)、三氯硅烷(HSiCl3)和六甲基二硅氮烷(Me6Si2NH)为原料，通过聚合物前驱体转化陶瓷(polymer-derived ceramics，PDCs)法成功合成了硅硼碳氮(SiBNC)陶瓷前驱体——聚硼硅氮烷(PBSZ)。采用傅里叶变换红外光谱、核磁共振、X射线光电子能谱、热重分析和差示扫描量热对PBSZ的结构和热性能进行分析。结果表明，PBSZ结构中存在硅氮硼(Si—N—B)网络和六元硼氮(B-N)环。在氮气中，800 ℃时PBSZ的陶瓷产率为53。9％。
Synthesis and Characterization of Polyborosilazane for Silicoboron-Carbonitride Ceramic
A silicoboron-carbonitride(SiBNC)ceramic precursor,polyborosilazane(PBSZ),was successfully synthesized using boron trichloride(BC13),trichlorosilane(HSiCl3)and hexamethyldisilazane(Me6Si2NH)as raw materials through the polymer-derived ceramics(PDCs)method.Fourier transform infrared(FTIR)spectroscopy,nuclear magnetic resonance(NMR),X-ray photoelectron spectroscopy(XPS),thermogravimetric analysis(TGA)and differential scanning calorimeter(DSC)were used to analyze the structure and high-temperature performance of the obtained PBSZ.Results showed that the network of silicon nitrogen boron(Si—N—B)and six-membered boron nitrogen(B—N)rings were presented in the PBSZ structure.The ceramic yield of the synthesized PBSZ at 800℃ in a nitrogen atmosphere was 53.9％.
