| 摘 要： | 用扫描电镜研究了3-硝基-1,2,4-三唑-5-酮(NTO)溶液在玻璃基片上挥发结晶行为,观察到随着NTO溶液的初始浓度升高,其晶体形貌从分形结构转变为立方状结构,并用扩散受限模型(DLA) 解释这一现象.通过傅立叶红外光谱(FTIR)和X射线粉末衍射(XRD)研究表明,分形结构和立方结构的NTO晶体属于同一种晶型,晶体形貌的改变并未造成NTO晶型的转变,仅分形结构的NTO晶体呈现了一定的择优取向,某些晶面出现优势生长. |

| Abstract: | The volatile solvent crystallization of 3-nitro-1, 2, 4-triazol-5-one (NTO) on glass substrate was studied. The observed phenomena verify that the crystal morphologies change from fractal to cube-shaped structure due to the initial concentration increasing,and it can be explained with diffusion limited aggregation (DLA) theory. Besides,the fractal and cube-shaped structure NTOs were characterized by FTIR, XRD. The results show that crystal morphology change can not result in crystal structure transformation, and only its growth-oriented change. |
| Keywords: | physical chemistry 3-nitro-1 2 4-triazol-5-one (NTO) crystal growth fractal structure cube-shaped diffusion limited aggregation (DLA) |
