For the problem of serious aggregation in nano-material synthesis, the new preparation method of monodisperse nano-metal oxide and its multiple compound was propsoed. The method was based on the study of sol-gel spontaneous combustion synthesis of nano-materials. Combined with the technology of explosives, shock wave produced in the thermal explosion may realize the effective separation of target product particles, eliminating the aggregation. The method was named as Gel Thermal Explosion Method. In the project, it was intended to adopt the method. The target products include NiZn ferrite and CuO. The project was to syudy the effect of the dosage of explosive(RDX as the representative), dosing process, etc. in the gel system on thermal explosion loose group, comparatively study spontaneous combustion method of gel and dispersion and performance of synthetic target products through thermal explosion method and explore the necessary conditions of thermal explosion formation of RDX in a gel system. Combined with numerical simulation, the multi-point and local-explosion deaggregation mechanism in gel system was proposed to provide theoretical support to monodisperse synthesis. The method provided an innovative idea for nano-materials deaggregation and also had the the same promotion significance for the preparation of other nanomaterials. |
