Spark Plasma Sintering

Our FAST/SPS technology allows rapid consolidation of powder materials. Among others, we are specialized in the processing and compacting of thermoelectric and topological nanopowders as well as composites. The simultaneous thermal and mechanical consolidation is realized by heating with high current and uniaxial pressure. This results in homogeneous volume heating and consolidation. Therefore, the powder is filled directly into the pressing tool that makes a pre-consolidation redundant.
