The synthesis of cordierite and anorthite by an all-alkoxide route has been demonstrated. Amorphous gel-derived anorthite powders are shown to exhibit crystallization behavior similar to that of melt-derived glasses. Crystallization of amorphous gel-derived cordierite powders takes place by the formation of a transient, metastable stuffed β-quartz phase, which converts to cordierite at higher temperatures - similar to the sequence of phase development in melt-derived glasses which are close to cordierite in composition.
