micro- and nano-particles of metal oxides, inorganic salts, metals
and organics.
Itcoversbasicprinciples,experimentalmethodologiesandreactors,particlep-

Fine
particlescanbeproducedbybothchemicalandphysicalprecipitationofproducts
from SCW. They can be used as catalysts, materials in ceramics and
electronic devices andcompositematerials.
