中文摘要：

采用高能球磨对合成一维β-SiC纳米材料的原料-Si粉和SiO2粉分别进行处理。通过正交试验研究球磨转速、时间、球料比、级配比等因素对球磨后粉体粒径的影响规律，结果表明，Si粉的球磨优化工艺为转速300r／min、球磨时间4h、球料比5：1，级配比Ф0mm：Ф10mm：Ф6mm：Ф2mm==1：50：180：400；SiO2粉的球磨优化工艺为转速350r／min、球磨时间4．4h、球料比15：1，级配比Ф20mm：Ф10mm：Ф6mm：Ф2mm=1：50：180：400。借助粒度分析仪及透射电子显微镜（TEM）对产物进行表征，发现经过球磨处理后的粉体粒度分布均匀，比表面积提高，可用以合成高质量的一维β—SiC纳米材料。

英文摘要：

Si powder and SiO2 powder as raw materials for synthesizing 1-D β-SIC nanomaterial th ough a chemical vapor reaction approach are treated with high-energy milling process. On the basis of several primary experiments, the influence of milling rotating speed, milling time, mass ratio of milling-bali/powder, blending ratio of milling balls on granularity of the podwer is investigated via the orthogonal experiments and the optimum processes were determined as follows that for Si powder, the rotating speed is 300r/min, milling time is 4 hours, mass ratio of milling-ball/powder is 5： 1, blending ratio of Ф20mm：Ф10mm： Ф6mm ：Ф2mm is 1：50：180：400, and for SiO2 powder the rotating speed is 350r/min, milling time is 4.4 hours, mass ratio of milling-ball/powder is 15 ： 1, blending ratio of Ф20mm： Ф10mm ：Ф6mm： Ф2mm is also 1：50：180：400. According to the results of granularity analysis and transmission electric microscope （TEM） characterization, the granularity distribution of as-gained products is homogeneous, and specific surface is increased significantly, which supports the synthesis of high quality 1-Dβ-SIC nanomaterial.
