| 英文摘要 | A novel liquid ZrB2/SiC precursor was prepared by the blend of polyzirconoxane and polyborosilazane, which were used as zirconium, silicon, boron and carbon source. The precursor was transformed into ZrB2/SiC ceramic during the pyrolysis, and its pyrolytic behavior, phase composition and microstructure were studied by TGA, XRD and SEM-EDX. The results indicated that the ceramic sample remained amorphous until t-ZrO2 initially generated at 1500 degrees C. Heating to 1600 degrees C led to the formation of ZrC via carbothermal reduction. Further heating to 1700 C led to the formation of ZrB2. During heat treatments, the compact ceramic sample became porous due to formation of CO and NO. The ceramic powder with particle size of 100-300 nm consisted of high crystalline degree ZrB2 and SiC phases, and all the elements were well distributed in ceramic powders. |
