| 摘 要： | 采用醇水混合溶剂热法于180℃合成了正交相氧化铪纳米粉体,用X射线衍射、透射电子显微镜和红外光谱对其进行了表征。结果表明:采用合适的醇与水的体积比,可在较低温度(180℃)制备出正交相纳米氧化铪。对合成的正交相氧化铪纳米粉经500℃硼砂熔盐处理可制备出短棒状单斜相氧化铪粉体。

| Abstract: | Orthorhombic HfO2 nanopowders were prepared in the mixed solution of alcohol and water at 180 ℃ via solvothermal method. The as-synthesized HfO2 nanopowders were characterized by X-ray diffraction,transmission electron microscopy,and Fourier infrared spectra. The results show that orthorhombic HfO2 nanopowders can be obtained in the mixed solution of alcohol and water in an appropriate ratio at a low temperature of 180 ℃. Short rod-shaped monoclinic HfO2 particles can be synthesized by the proposed method of synthesizing orthorhombic HfO2 nanocrystals with borax as addition agent,and then followed by heat-treatment at 500 ℃. |
