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Φ20mm:Φ10 mm:Φ6mm:Φ2mm=1:50:180:400;SiO2粉的球磨优化工艺为转速350 r/min、球磨时间4.4 h、球料比15:1,级配比Φ20mm:Φ10mm:Φ6mm:Φ2mm=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.
