Spark Plasma Sintering
Spark Plasma Sintering (SPS) is a non-conventional sintering technique characterized by the application of high uniaxial pressure and high intensity pulsed current to the sample that allows obtaining very fine microstructures in short periods of time as well as avoiding transformations of undesirable phase and the use of sintering additives.
