In nanocomposite synthesis, researchers using Hydrothermal Autoclave Reactors during synthesizing the materials within a closed system.
I need a thorough answer and good explanations.
Hydrothermal synthesis takes place in autoclaves. These sealed cylinders can endure high pressure and temperature for a long duration to provide an ambient condition for nanomaterials synthesis. Hydrothermal synthesis is a very powerful tool for producing various functional nanomaterials of transition-metal compounds, such as oxides, hydroxides, and sulfides. In many cases, self-organized hierarchical nanostructures, such as nanoflowers and nanourchins, can be obtained spontaneouslyThe 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. Advanced sciences rank nanotechnology as one of the driving forces with the potential to revolutionize material science of the current age. For the synthesis of nanoparticles, the process of the hydrothermal method is being increasingly favored globally, by industries and R&D labs alike. In easy terms, hydrothermal synthesis described as an artificial way to synthesize single-crystal (nanoparticles). Also, It depends on the solubility of aqueous solution under hot water and higher temperature levels. A strong container within the hydrothermal reactor ‘Autoclave,’ and fill with a solution. The process wants constant maintenance of temperature difference between the opposing ends of the crystallizing compartment.
Hydrothermal technique
hydrothermal processes need to use solutions having a corrosive impact on the interior material of the autoclave

In addition to the answer Prem Baboo . For example, titanium dioxide nanoparticles can be obtained by the sol/gel method and hydrothermal method.
The advantages of the sol/gel are the absence of a high pressure reactor. Disadvantages high temperature at the last stage of calcination.
The advantage of the hydrothermal method is the low synthesis temperature. Synthesis of some modification of crystalline titanium dioxide. Lack of synthesis in an autoclave.

You should have written: "Hydrothermal processes must use solutions that are not corrosive to the internal materials of the autoclave."
