Summary
Non stoichiometry in mullite induces super structure formation and low atomic mobilities. Some variations in composition, stability, and microstructure of mullite are reviewed as a function of the synthesis processes and the related ability for ion to diffuse and a-alumina to nucleate. An example of a glass free mullite/alumina in situ composite formed from a high A12O3 to SiO2 ratio composition is described. The high strengths and creep resistances obtained are counterbalanced by a great sensitivity to alkali contamination.
