Synthesis of New Materials Under High Pressure Conditions.

Abstract

Several examples will be selected for illustrating the different abilities of high pressure synthesis through the different routes described.A discussion will propose, for the future, some routes for developing pressures in Materials Science.

Recent advances in hydrothermally and solvothermally grown Co3O4nanostructures for electrochemical energy storage (EES) applications: a brief review

“…These techniques help to increase the knowledge of the correlation between composition, structure, chemical bonding, and resulting physicochemical properties of materials. 51 Hydrothermal and solvothermal methods involve thin film synthesis at high pressures (about 1 atm to several kilobars) and high temperatures (about 100-10 000 1C). 52 Hydrothermal synthesis involves chemical reactions in an aqueous solution (water as solvent) above the boiling point of water.…”

Crystal and Electronic Structures of MoSi2-Type CrGe2 Synthesized under High Pressure

“…Intermetallic compounds, which crystallize in structures different from those of metal elements and their solid solutions, have attracted attention because of their various properties, including magnetism, hardness, and superconductivity . High-pressure synthesis is a suitable technique for the synthesis of intermetallic compounds because chemical reactions are often promoted by volume reduction under high pressure considering Le Chatelier’s principle . Some intermetallic compounds become only thermodynamically stable at pressures on the order of gigapascals (GPa). − Many of them were synthesized below 10 GPa using a large-volume multianvil press (LVP).…”
