In the reaction temperature of 230 degrees , n (Fe2 +) / n (Fe3 +)is 0.1, and the total concentration of Fe is 1.25 mol/ L and the seed crystal is 2gb, change under the condition of n( Fe2 +) /n (Fe3 +) or 0.04 or total concentration of 1.875 mol Fe/ L, hydrothermal products of alpha Fe2O3 for spheroids, Change the seed crystal of 0g, hydrothermal products as directed globular alpha Fe2O3. Change the reaction temperature for 140 degrees Celsius n(Fe2 +)/n (Fe3 +), income hydrothermal 0.12 phase of product for the alpha Fe2O3 and alpha FeOOH or alpha Fe2O3 and Fe3O4. |
