Spark Plasma Synthesis (SPS) Device for Sintering of Nanomaterials

It is known that work pieces with nanocrystalline structure condition have much higher performance than those with an ordinary structure. There are known number of techniques for manufacturing of nanocrystalline materials in powder condition however a question of manufacturing bulk pieces in the same nanocrystalline state mentioned is that compaction and synthesizing of nanocrystalline powders are accompanied with intensive growth of particles – the process which promotes to formation of pieces in an ordinary crystalline state instead of being crystallized in the desirable nanocrystalline state. Most promising method for fabrication of pieces with the preserved nanocrystalline structure is compaction and sintering by using Spark Plasma Synthesis (SPS) process. Present work is dedicated to the problems and advantages of the SPS process which provides synthesis of composites with nanocrystalline structure.
