Mullite Formations

Comprehensive presentation of six synthesis processes of mullite precursors, such as gelation, coprecipitation, diphasic gelation, codecomposition, and microcomposite processes, are shown. Comparison of phase evolution processes of spray pyrolysis, monophasic, polymeric, coprecipitated, diphasic precursors and composite mullite powders is established.Critical analysis of the results of DTA, XRD, IR, and MAS NMR of earlier researchers, as shown in Review part of the book, is included.Chemistry behind the hydrolysis reaction of different components in six synthesis processes of mullite precursors in achieving homogeneity is shown.Elaborate discussion of the characterization of Al-Si spinel and t-mullite based on studies of alkali leaching, TEM/EDS, QXRD, and lattice constant measurements is done.Remarkable of diagrams/graphics are included in each chapter.
