The mechanochemical–hydrothermal synthesis utilizes aqueous solution as a reaction medium. Mechanochemical activation of slurries can generate local zones of high temperatures (up to 450–700°C) and high pressures due to friction effects and adiabatic heating of gas bubbles (if present in the slurry), while the bulk system is close to room temperature [400] .

As described earlier, continuous hydrothermal synthesis is probably the most effective method for the scale-up approach. However, an additional process in this method is necessary for surface modification. Figure 24.9 shows the scheme of the ideal scale-up process to prepare surface-modified iron oxide nanoparticles. In this system, aqueous metal salts and organic surfactants …

Hydrothermal Synthesis. Many sample preparation techniques require an aqueous mixture to be heated above 100°C resulting in the system having an associated vapor pressure. Examples of this are nanoparticle and zeolite synthesis. Many of these methods also require either acid or alkaline conditions where stainless steel would be readily corroded.
