| 摘 要： | 采用红外光谱技术和光电子表面能谱技术比较纳米和微米氮化硅粉体表面结构在空气中和在氮气中的变化规律.研究结果显示,纳米氮化硅在空气中逐渐吸附氧气和有机物质,其表面形成了Si—OH、C—C、C—N等化学基团,而在惰性的氮气气氛中,纳米氮化硅的表面氧化被有效抑制.上述研究工作为纳米氮化硅的表面改性研究提供了一定的理论支持.

| Abstract: | In this paper,surface structure's change regularity of nano-and micro-silicon nitride powder in air and nitrogen atmospheres was studied by FT-IR and XPS.The results showed that nano-silicon nitride in air gradually absorbed oxygen and organic matter,and Si—OH,C—C,C—N groups were produced on the surface of nano-silicon nitride.While in an inert atmosphere(N2),surface oxidation of nano-silicon nitride can be effectively suppressed.This work will be a helpful mechanism research on the surface modification of Si3N4 nanopowder. |
