| 摘 要： | 通过ＡＦＭ研究，发现硅质煤矸石的两种主要组成ＳｉＯ２和Ｃ具有纳米粒状结构和纳米层状结构．ＳｉＯ２纳米颗粒的尺度为３～２０ｎｍ，Ｃ质纳米颗粒的尺度为１０～２０ｎｍ．纳米层厚为５～８０ｎｍ．矸石中的ＳｉＯ２和Ｃ呈密接触状态．用这种结构的煤矸石为原料，在１３００℃时就可合成β－ＳｉＣ，其合成温度明显低于人工混合物料同等条件下的合成温度，而且产率也可大幅度提高．

| Abstract: | The nanoparticle structure and nanolayer structure of SiO2 and C in a silicious gangue were found by Atomic Force Microscope. The size of nanoparticle SiO2 is 3~20nm, the size of nanoparticle C is 10~20nm and the thick of nanolayer is 5~80nm in the gangue. SiO2 and C in the gangue are contacted tightly each other.β-SiC ultrafine powder was synthesized at 1300℃ with the gangue. The temperature is lower obviously than that synthesizing SiC with other raw materials mixed under the same conditions. And SiC yield can also be increased greatly. |
