Recently,the study on the SiC one-dimensional nanomaterials have attracted extensive attention. However, how to achieve the continuous preparation of mass production and the study of the related basic theories are still in blank states at home and abroad. In this project, continuous preparation of massly SiC one-dimensional materials is innovatively carried out in a larger reaction space by an atmosphere controllable smart furnace which is developed independently, and the associated basic theories are studied. Main research contents: 1) According to the structural features of the atmosphere furnace, the flow field and temperature field contours in the larger reaction space (Material box) are simulated by fluent software, and then establish the numerical theoretical model. To use the above simulated results as guidance, the material box is optimized and improved which will ensure that uniform SiC one-dimensional materials are acquired; 2) The effects of various process parameters on the production, morphology and quality of the continuous preparation of SiC one-dimensional nanomaterials are systematic studied, and then optimal process parameters are obtained. According to growth of mesoscopic thermodynamics, dynamics and crystal growth theories, the growth model is established in theory. 3) The microscopic growth process and growth mechanism of SiC one-dimensional materials under different parameter are simulated by Gauss and material Studio software. The influence of process parameter on the growth rate and morphology of the products are theoretically explored.
