摘　　要：本文利用ＸＰＳ谱研究了ＣＯ２激光驱动气相合成的ＳｉＣ纳米微粉的氧化特性，对于纳米微粉的制备工艺控制以及储运有参考价值。Abstract In this papaer,the oxidative characteristics of nanometer sized SiC parti-cles which is vapor-synthesized by laser induced is studied using XPS,Ex-periments showthat the extent of oxidation does not change very much at the temper-ature of 20℃ in 1atm,but at the temperature of 200℃-1000℃,the extent of ox-idation increases with thetemperature increase,This is valuable for synthesizingand preserving nanometer sized SiCparticles.
