The high-temperature hafnium nitridation process, with HfN_x formation, comprises two stages. With increasing nitridation temperature and time, the lattice parameter of the nitride decreases. The observed discrete nucleation of nitride microcrystals on the surface is a consequence of metal diffusion through an amorphous carboxynitride. No structural defects were detected by high-resolution transmission electron microscopy in selected areas.
