摘要
采用XRF、SEM、XRD、NMR、TEM等测试手段对苏州和茂名高岭土及其650℃煅烧产物进行了研究。实验结果表明:煅烧产物由煅烧前的晶态转变成了非晶态,Al由六配位转变为四、五、六配位共存,煅烧前高岭土结构致密,煅烧后产物结构变得疏松。
The microstructure of kaolin and kaolin fired were studied by XRF, SEM, XRD, NMR and TEM. The results showed that the kaolin fired had been transformed from crystallized kaolin to non-crystal, and some Al^ Ⅵ had transformed into Al^Ⅳ, Al^Ⅴ. So the structure of kaolin is compact, while the structure of kaolin fired is loose.
