摘要
采用29Si、27AlMASNMR谱对不同产地高岭在同一煅烧温度及同一产地高岭土在不同煅烧温度的煅烧产物进行了研究.实验结果表明:不同产地高岭土在同一煅烧温度煅烧产物的29SiMASNMR相似,27AlMASNMR谱有所区别,煅烧温度对煅烧产物的29Si、27AlMASNMR有一定影响.
^29Si and ^27 Al MAS NMR spectra of calcined kaolin coming from different regions and kaolin calcined at different temperatures were acquired and compared. The resuits showed that the ^29Si spectra of calcined kaolin coming from different regions were similar while the ^27Al spectra were different. Calcination temperature was found to influence the ^29Si and ^27Al spectra of calcined kaolin obtained from the same area.
