| 摘 要： | Nano-sized HfO2, C and C/HfO2 powders obtained through hydrothermal process have been investigated by XRD, TEM and FTIR, and Different precursors, namely Hafnium(Ⅱ) oleate and Hafnium(Ⅱ) hydroxide derived from homogeneous precipitation method, have been chosen for the synthesis of nanometric HfO2 via hydrothermal process. The results indicate that using the former material as the precursor under identically hydrothermal process can yield finer HfO2 nanoparticles, compared to using the latter. Nano-sized Carbon of about 100 nm with square morphology and narrow size distribution can be obtained through hydrothermal reaction of sucrose solution at 200 ℃ for 6 h. The addition of as-synthesised Carbon nanoparticles into the hydrothermal process of HfO2 powder can produce C/HfO2 composite powders with core-shell structure.
