| 摘 要： | 选择廉价的六甲基乙硅胺烷－（Ｍｅ３Ｓｉ）２ＮＨ和氮气为原料进行激光诱导气相反应，通过交变化激光功率密度及反应气流量，制备具有较宽组分变化范围的Ｓｉ／Ｎ／Ｃ纳米粉。用化学分析，ＴＥＭ，ＳＡＸＳ，ＢＥＴ，ＩＲ，ＸＲＤ等测试手段对粉末进行了表征，结果表明此Ｓｉ／Ｎ／Ｃ粉主要由Ｓｉ－Ｎ和Ｓｉ－Ｃ键构成，是Ｓｉ，Ｎ，Ｃ组成的无定型物，由于实验条件的不同会不同程序地导粉末中存有有机杂质。

| Abstract: | The Si/N/C nanopowder with a wide composition range was synthesized from hexamethyldisilazane and ammonia by laser induced gas phase reactions under the orthogonal design of laser power density and two reactant flow rates. The powder produced was characterized by chemical analysis,TEM,SAXS,IR and XRD. The Si/N/C powder is an amorphous compound consisted mainly of Si-N and Si-C bonds and some organic substances which depends on the synthesis processing parameters. |
