THE ^(29)Si AND ^(27)AI MAS NMR SPECTRA OF MULLITE SINTERED AT DIFFERENT TEMPERATURES
THE ^(29)Si AND ^(27)AI MAS NMR SPECTRA OF MULLITE SINTERED AT DIFFERENT TEMPERATURES
摘要
Since 1980, the solid-state high resolution NMR techniques have been introduced into mineralogy, and the magic-angle spinning (MSA)NMR technique has been extensively used. Mullite is an important synthetic mineral material. The mechanism of
