Materials based on aluminum and iron oxides obtained by the hydrothermal method

The influence of the relation [Al 3+ ] : [Fe 3+ ] on the phase composition and morphology of the products obtained by the hydrothermal method using solutions of salts of metals and combined sols of aluminum and iron (3+) hydroxides has been studied. The hydrothermal treatment of solutions of salts o...

Description
Summary:The influence of the relation [Al 3+ ] : [Fe 3+ ] on the phase composition and morphology of the products obtained by the hydrothermal method using solutions of salts of metals and combined sols of aluminum and iron (3+) hydroxides has been studied. The hydrothermal treatment of solutions of salts of aluminum and iron (3+) results in the formation of hematite of a cylindrical or capsular shape, while by the treatment of sols, depending on the relation [Al 3+ ] : [Fe 3+ ], it is possible to obtain particles of hematite with an ellipsoidal shape or bundles of amorphous AlOOH.
