中文摘要：

利用极性有机分子十二烷基胺插层高岭石，葡萄糖层间取代的方法合成高岭石-葡萄糖插层复合物。以高岭石．葡萄糖插层复合物为前驱体，采用原位碳热还原、氮化反应技术，在1450℃保温4h，以500mL／min的N2流量的反应条件合成了Sialon粉体。并运用XRD、FT-IR、TG、DSC等技术表征反应过程和产物特征。研究表明，十二烷基胺插层复合物中，高岭石的d001值扩大为2．280nm，高岭石．葡萄糖插层复合物中，高岭石的d001值由0．717nm扩大为3．364nm，插层率达87％。插层复合物原位碳热还原、氮化反应研究表明，产物中结晶相主要有：Sialon相（以β-Sialon为主）和少量莫来石。高岭石插层复合物原位碳热还原、氮化反应能在较低的温度下合成β-Sialon，是一种新颖而有效的方法。

英文摘要：

Kaolinite-glucose intercalation compound was synthesized by intercalating of kaolinite with large polarised organic molecule, such as dodecylamine, and replacing in the layers of kaolinite with glucose. Sialon powder was produced using kaolinite-glucose intercalation compound as precursor by carbothermal reduction and nitridation （CRN） at 1450℃ for 4 h and with N2 flux of 500 mL/min. The reactions during synthesis were studied and the products were characterized with XRD, FT-IR, TG and DSC. The results indicated that the basal spacing of kaolinite-dodecylamine intercalation compound increased from 0.717 nm to 2.280 nm and that the basal spacing of kaolinite-glucose intercalation compound increased to 3.364 nm, and that intercalation rate reached 87%. The CRN of intercalation compound indicate that in the products Sialon （giving priority to β-Sialon） and a little mullite are main phases. The in-situ earbothermal reduction and nitridation processing of kaolinite is a novel and effective method for Sialon synthesis at lower temperature.
