中文摘要：

分别以四氯化锆和双酚A或对苯二酚作为锆源和碳源合成了几种可溶性Zr C前驱体。利用傅立叶红外光谱（FTIR）对前驱体的结构进行了研究,并采用X射线粉末衍射（XRD）、扫描电镜（SEM）和能谱仪（EDS）对前驱体不同温度热处理后的裂解产物进行了表征。结果表明,以锆源与碳源物质的量之比为1∶1时所制备的前驱体在1600℃裂解后能完全转变为颗粒尺寸约为100 nm的Zr C陶瓷粉末,当锆源与碳源物质的量之比为1∶2时,碳源过量致使前驱体中氧含量相对过高而无法完全转化为Zr C陶瓷相。

英文摘要：

Several soluble precursors for zirconium carbide were synthesized by using zirconium tetrachloride and bisphenol A or hydroquinone as a zirconium source and carbon sources, respectively. The structures of the precursors were examined by FTIR. The microstructure and the phase composition of the pyrolysis products of the precursors at various temperatures were analyzed by XRD, SEM and EDS. The results show that the precursors prepared by the molar ratio of the zirconium source and the carbon sources 1 ∶ 1 can completely transformed into Zr C ceramic powders with particle size of about 100 nm at 1600 ℃. When the molar ratio（of the zirconium source and the carbon sources） was changed into 1 ∶ 2, the precursors cannot convert to pure Zr C ceramic phase because of the high oxygen content caused by the excess of the carbon source.
