Abstract:

Research activities supported by a nine-month Short Term Innovative Research (STIR) grant from the Army Research Office, Materials Science Division, Synthesis and Processing of Materials Program are disclosed herein, comprising: synthesis of selected mixed oxide and non-oxide ceramic solid solution powders via conventional solid state techniques; gas-solid reaction processing to produce ceramic nanocomposite particles; and, on a limited basis, bulk consolidation via spark plasma sintering. Microstructural characterization of products was conducted viaelectron microscopy and x-ray diffraction.
