采用在玻璃基片上溶剂挥发结晶的方法制备出了具有分形结构的树枝状3-硝基-1,2,4-三唑-5-酮(NTO)晶体,并通过SEM、FTIR、XRD、TG-DSC等对这种结构的晶体进行了分析表征。结果表明:这种分形结构的NTO晶体与溶液中重结晶的立方状NTO同属于α晶型.分形结构的NTO晶体呈现了一定的择优取向,且这种分形结构的NTO晶体未对其热性能造成明显的影响。
Dendritic 3-nitro-1,2,4-triazol-5-one (NTO) crystals with a fractal structure were prepared by solvent evaporation crystallization on a glass substrate and characterized by SEM, FTIR, XRD, -DSC and other structures of this crystal were analyzed and characterized. The results show that the NTO crystals with the fractal structure and the cubic NTO crystals recrystallized from the solution belong to the α crystal form, and the fractal structure of the NTO crystal exhibits a certain preferred orientation, and the NTO crystal of this fractal structure has no influence on the thermal properties Caused a significant impact.
