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.
