Abstract
Diamond was synthesized from graphite in SCW at high temperatures and ultra-high pressures (∼3,273 K, 10 GPa) for long time (e.g., 24 h). Many inorganic phosphates were produced that have important industrial uses, e.g., as catalysts, ion-exchange materials, solid electrolytes for batteries and synthetic replacements for bones and teeth. Submicron particles of LiFePO4 were produced in SCW from \(\{ {\textrm{FeSO}}_4 + o-{\textrm{H}}_3 {\textrm{PO}}_4 + {\textrm{LiOH}}\}\) solution in batch and flow reactors. Much smaller and more uniform particles were found in rapid continuous synthesis than in batch hydrothermal synthesis. Micron-sized KCo3Fe(PO4)3 and Mg3.5H2(PO4)3 crystals were also produced in batch reactors. At the same time, amorphous nanoparticles of KxCoyFezPO4 and Fe1−yKyPO4 were obtained.
