| Popis: | The oxidation behavior of iron powder with oxygen was investigated in 5-25 m NaOH solutions at 5 MPa of oxygen partial pressure and 130-290 o C, where m=mol(kg H 2 O) -1 . Monodispersed micaceous iron oxide, α-Fe 2 O 3 , was synthesized by the oxidation of iron powder with 5 MPa of oxygen in 10-16 m NaOH solutions at 250-270 o C. The diameter of micaceous iron oxide greatly changed depending on the reaction conditions such as the temperature, reaction time and concentrations of NaOH and coexisting ions. |
