| 摘 要： | 激光气相法是制备超微粉末的新方法之一,目前还存在超微粉末粒径太小难于收集,原料SiH_4价格较昂贵等困难。我们以SiH_4为主要原料,成功地合成出超微Si、Si_3N_4、SiC粉末,研究了反应条件对超微粉性能的影响,探索了用廉价原料代替SiH_4的可能性,并且在超微粉的收集方面做了若干探索,取得了一些有意义的结果。

| Abstract: | In the present paper, the principles and devices for producting ultrafine powders by laser induced vapor-phase reaction method is presented. The ultrafine powders of Si, Si_3N_4 and SiC is successfully prepared with a 150W CW CO_2 laser as light source and SiH_4 as main raw- material. The influence of experimental conditions on properties of ultrafine powders is investigated. The pooossibility of substitution of cheaper materjals for SiH_4 is also discussed. This study is expected to mave a good prospects in industrial applications. |
