中文摘要 | Grain evolution of nano-crystals ZnO under high temperature and pressure is studied using a cubic high pressure apparatus. The structure, grain sizes and morphology of the samples are characterized by X-ray diffraction and field emission scanning electron microscopy. The results show that the grain sizes of ZnO grow rapidly at temperature 200 degrees C under pressure. At temperature lower than 300 degrees C (including 300 degrees C), the grain sizes of the samples first increase with the pressure increasing from 1 to 3 GPa and later decrease from 4 to 6 GPa. The activation volume from 1 to 3 GPa and from 4 to 6 GPa is calculated respectively using the phenomenological kinetic grain growth equation at temperature 300 degrees C. At temperature higher than 400 degrees C (including 400 degrees C), the grain sizes of the samples increase with the pressure increasing from 1 to 6 GPa. ZnO nano-bulks with good quality can be obtained under the specific conditions. |
