N2 - Numerous sintering studies have been published concerning the innovative Spark-Plasma-Sintering (SPS) procedure during the last years. A wide variety of materials (such as oxidic and non-oxidic ceramic powders, metal and composite samples) with different particle size (submicron and nanoscale), various electric, thermal, and mechanic properties have been studied. The influence of the SPS process on the evolution of the phase composition has been studied. The goal of the work on the SPS process performed at the Austrian Research Centers Seibersdorf (ARCS) with collaborations partners at Nanyang Technological University (NTU) in Singapore is the critical comparison of the method with different competitive compaction methods such as pressureless sintering, hot pressing, or gas pressure sintering. For that purpose various mechanical and structural parameters e.g. sintering density, hardness, crystallite size, chemical composition were determined. The work at ARCS was focused on the topics 1) submicron powders, and their grain-growth behaviour during the densification process. 2) refractory metals and their densification properties 3) copper and copper based composites Finally a review of the current situation of the SPS method from a more technological viewpoint will be given. The requirement for a successful industrial application of this new method will be discussed.
