Synthesis and Characterization of Polyborosilazane for Silicoboron-Carbonitride Ceramic
摘要
Abstract
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％.关键词
