Spark plasma sintering is being increasingly employed in the field of sintering to increase the level of solid chemistry reaction that induces a decrease in the sintering temperature over a shorter duration by limiting grain growth. Spark plasma synthesis focuses on a new approach in advanced materials, such as the assembly of various materials (multimaterials), the densification of composites less than their melting temperatures, the welding of metal alloys, electromigration, etc. The application of high pressure in SPS—instead of conventional pressure which is restricted to the use of graphite molds—with other types of molds allows a new high-pressure field in materials science for refractory compositions, high-pressure phases (diamond, cubic boron nitride, etc.), phase transitions, hydro(solvo)thermal, etc., for innovative fields of application. Combination of the spark plasma process using high-pressure tools for material synthesis will be addressed in this Special Issue. This Special Issue, titled “Spark Plasma Synthesis under High Pressure for Advanced Materials” aims to cover an overview of innovation in high-pressure processes/technologies for the synthesis of advanced functional inorganic materials. To this end, we are pleased to invite you to submit a manuscript to this Special Issue. Full articles, papers and reviews are welcome. Dr. Alain Largeteau Dr. Mythili Prakasam Guest Editors
