wet chemical methods
(rus. "мокрая" химия)
—
common (slangy) name for a group of methods used for producing nano- and ultra-dispersed inorganic powders from aqueous and non-aqueous solutions.
Description
The term "wet chemical methods" emerged in contrast to conventional and solid-state synthesis methods of compounds and materials widely used also in ceramics manufacturing. Today the term refers to a group of methods of powder and material production (liquid phase sol-gel process, hydrothermal synthesis, Pechini method, spray drying, aerosol spray pyrolysis, cryochemical synthesis, etc.) using liquid phase at one of the process stages. The main differences between wet chemistry products and similar products of solid-phase synthesis are much smaller grains (crystallites) and, usually, lower temperature and shorter duration of phase formation.
