The basic features of Soft Solution Processing are discussed. Pioneering research carried out in our laboratory on in situ fabrication of morphology-controlled advanced ceramic materials by Soft Solution Processing (synthesis of double-oxide ABO(3), ABO(4) films by hydrothermal, electrochemical, hydrothermal-electrochemical methods, coating of CaTiO3 on TiAl, preparation of carbon films on SiC, hydroxyapatite whiskers and fine powders under hydrothermal conditions) is reviewed. Soft Solution Processing allows us to fabricate in aqueous solutions shaped/sized/oriented ceramics in only one step, without excess energies for firing/sintering or melting, and without expensive equipment, providing an environmentally friendly route for the preparation of advanced ceramic materials.
