The microstructural evolution of sintered mullite prepared from a premullite powder after thermal treatments at 1570°C was observwed by transmission electron microscopy and energy‐dispersive X‐ray microanalysis. The results show that there are grains with lower and higher contents of Al 2 O 3 than that in stoichiometric mullite and small glassy‐phase areas with the same composition as mullite; α‐Al 2 O 3 precipitates after samples are annealed.
