Abstract
A microstructural study of mullite obtained by the reaction sintering of ka olinite-alpha-alumina mixtures in the range 1150-1700 degrees C has been pe rformed by using X-ray line profile analyses together with scanning and tra nsmission electron microscopy equipped with microanalysis by energy dispers ion (SEM-EDS, TEM-AEM). Two kinds of morphology corresponding to primary (e longated grains) and secondary (equiaxed grains) mullite have been observed . A bimodal crystallite size distribution has been detected through XRD mic rostructural analysis from 1300 degrees C. The results obtained by this met hod are compared with SEM/TEM data.
