Cool-SPS: an opportunity for low temperature sintering of thermodynamically fragile materials

Sintering has been achieved by Spark Plasma Sintering at low temperatures ( 90% of theoretical density) fragile materials, and also highlights the extra stability afforded by this approch for certain materials which have been sintered above their normal decomposition temperature. Using multiple examples, this work illustrates the potential of “Cool-SPS” for fast and efficient sintering of fragile materials which are impossible to sinter by conventional sintering techniques.
