What is the SPS Process?
The Spark Plasma Sintering (SPS) Process is easy, cost effective, and requires no previous
sintering experience. And, its diversity-the wide range of materials available and high-speed processing
makes possible the synthesis of materials and components from metals, ceramics, polymers and composites
to highly advanced FGMs, and thermoelectric semiconductors.
