The morphology and microstructure of an Al2 O3 glass composite (trade name In-Ceram, Vita Zahnfabrik) were studied using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The composite was produced by infiltration of a lanthanum-based glass throughout a porous Al2 O3 body. This alumina body was formed by three classes of particles differing in size and shape: faceted particles typically
