A novel microwave reactor was used to hydrothermally synthesize
nanopowders of iron oxides under pressures up to 10 MPa and
temperatures of up to 250 o C. At reaction times as short as 5 min it
was possible to synthesize powders with grain size 10 - 100 nm. Proper
selection of the substrates and their concentration permitted to
control to some extend the grain size and phase composition. Pure
hematite, maghemite and magnetite could be obtained.
