Hydrothermal synthesis refers to the synthesis of substances via chemical reactions in a sealed and heated solution above ambient temperature and pressure. The concept 'hydrothermal' originates from earth science in the nineteenth century, where it implies a regime of high temperatures and water pressures ( Byrappa and Yoshimura, 2001 ).
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.
