29Si and 27Al MAS NMR spectra of mullites from different kaolinites
He, Hongping, Guo, Jiugao, Zhu, Jianxi , Yuan, Peng, & Hu, Cheng (2004) 29Si and 27Al MAS NMR spectra of mullites from different kaolinites. Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 60(5), pp. 1061-1064.
Mullites synthesized from four kaolinites with different random defect densities have been studied by 27Al and 29Si magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR) and X-ray diffraction (XRD). All these mullites showthe same XRD pattern. However, 29Si and 27Al MAS NMR spectra reveal that the mullites derived from kaolinites with high defect densities, have a sillimanite-type Al/Si ordering scheme and are low in silica, whereas those mullites derived from kaolinites with low defect densities, consist of both sillimaniteand mullite-type Al/Si ordering schemes and are rich in silica.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
