    Abstract

    The structure of aluminum nitride ceramic, regardless of the type of oxides additives, is characterized by the presence of defect-free regions of coherent scattering with a size of about 0. 1 mu m contained within crystallites with a mean size of about 3-4 mu m. The crystallites are incorporated into conglomerates with a size of about 10 mu m. Additives which improve sintering, although they are contained mainly at the boundary of the AlN crystalline phase, greatly affect the ceramic structure - namely, the size and shape of the AlN crystallite conglomerates, the size of the crystallites, the size of the coherent scattering regions, the dislocation density, and the stacking fault concentration, but have no effect on the elementary cell parameters.
