Many sample preparation techniques require an aqueous mixture to be heated above 100C 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. Parr Instrument Company manufactures a …

The Hydrothermal Autoclave Reactor use to carry hydrothermal reaction at high pressure and high temperature. Hydrothermal synthesis reactor generally comes in a two variety; the first is Polytetrafluoroethylene (PTFE) or Teflon lined hydrothermal autoclave reactors and the second is PPL lined autoclave.
More details
The Teflon-lined hydrothermal synthesis autoclave is corrosive resistant. It is also acidic and alkaline resistant hence used for highly alkaline and acidic solutions. The autoclave for hydrothermal synthesis mostly used for crystallization processes and nanoparticles.

This study evaluated the reaction kinetics of hydrothermal synthesis for the nickel nitrate to nickel oxide reaction that occurs in a wide range of temperatures and pressures around the critical point of water. The effects of mass transfer on the reaction rate were evaluated using a two-flow mixing system from which the relation between the mass transfer rate and Re …
