[alpha]-Si[sub 3]N[sub 4] core structures within [beta]-Si[sub 3]N[sub 4] grains have been studied by transmission electron microscopy. The grains were dispersed in an oxynitride glass which was previously melted at 1,600 C. The cores were topotactically related to the as-grown [beta]-Si[sub 3]N[sub 4] crystallites and are related to epitactical nucleation during heat treatment as the most probably mechanism.
