Hydrothermal Synthesis. 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.
