Abstract Scope In this study, we report the fabrication of aluminum oxide filter via spark plasma sintering for application as a hot gas filter. Spherical alpha alumina particles were sieved to achieve uniform size distribution. A bimodal size distribution was observed, after sieving, of 180▒40 Ám and 109▒16 Ám, for the large and small particle respectively. Powder was then sintered via spark plasma sintering at varying dwell temperatures, pressures, and dwell periods to find optimal parameters to produce sufficient surface diffusion at necks between particles. A temperature of 1500C, 30 minutes dwell period, and 10MPa applied pressure produced filters with optimal range of densification. Samples were then characterized by scanning electron microscopy (SEM) for porosity measurements and pore/neck formation between particles. A test rig to evaluate the filtering characteristics of Al023 filter is being developed. These tests will be conducted via inert gas flowed through quartz tube furnace at 600C.
