摘要
采用激波等离子法制备了C/ZrO2纳米复合粉体。通过X衍射、拉曼光谱对复合粉体的晶相组成进行了分析,利用透射电镜(TEM)对复合粉体的粒度、形貌进行了表征,借助热重分析对粉体的组成进行了检测,进一步对粉体的制备机理进行了探讨。结果表明:激波等离子体法可实现C/ZrO2纳米复合粉体的快速制备,所制备出粉体的粒径在10 nm左右,复合粉体中碳为石墨相,约占总量的63%(质量分数),氧化锆占总量的37%,主相为四方相。
Nanometer carbon/zirconia compound powder was synthesized via novel shock wave plasma technique. X-ray diffraction and Raman spectrum were respectively used to characterize the crystal phase composition of the compound powder. Transmission Electron Microscope was used to observe the size and appearance of the as-synthesized powder, precursor and the as-synthesized product. The composition of the compound were tested through DTA/TG analysis. The preparation mechanism was also discussed. The results indicated that the carbon/zirconia compound powder of 10 nm in diameter was synthesized via shock wave plasma technique. The components of the compound powder include 63% （mass fraction） graphite and 37% tetragonal zirconia.
