In this paper, the development of the synthetic method of our country and abroad was investigated. The nanomaterials have great applications in every field for the unique properties that general materials do not possessing. We developed a new method to the synthesis of nanomaterials after studing the fabrication method that used by other researchers from the published papers. In our paper, we first synthesized the nanoparticles of some compounds at the room temperature in a solid-state reaction, and then the nanoparticles were used as precursors and heated in the molten salt circumstance at different temperatures. Then different morphologies of nanomaterials such as hollow spheres of manganese oxide, nanorods of copper oxide and nanobelts of tin oxide were successfully fabricated. We studied the influence of different parameters in the fabrication process such as the reagents, the heating temperature, heating time and different salts on the morphology of the last sample of the nanomaterials. The optimal synthesis condition was confirmed. We investigated the growth mechanisms of the growth of nanomaterials that synthesized at different conditions, and put forward the solid-state growth mechanism of nanomaterials for the good explanation of the nanomaterials synthesized in our experiments.
