Results of an IR absorption characterization of alpha silicon nitride specimens prepared in the laboratory by several different procedures are presented. The results suggest the presence of bulk oxygen in the silicon nitride lattice. It is concluded that, although it is not necessary that alpha silicon nitride have bulk oxygen to stabilize its structure, it can accommodate a considerable amount of bulk oxygen without becoming oxynitride structurally.
