Abstract

Different analytical techniques have been used to characterize green and sintered sol-gel processed cordierite on a microscopic scale. The sintered material, although identified macroscopically as α-cordierite, contains many small precipitates of different chemical composition. Larger precipitates, characterized by an increased Mg concentration, result from inhomogeneities in the precursor gel. Smaller precipitates, identified as mullite and spinel, could not be related to gel heterogeneities. The amorphous phase surrounding the cordierite grains and the precipitates is Mg depleted and Si enriched. Neither μ-cordierite nor β-cordierite were observed; slight variations of the α-cordierite lattice parameters are attributed to some local perturbations due to a slight departure from stoichiometry or Si, Al ordering on tiny domains.
