摘要：

Mixtures of magnetite and goethite were formed by the slow oxidation of mixed FeCl2-AlCL3 solutions in an alkaline environment at room temperature. The compositions of the products ranged from almost exclusively magnetite in Al-free systems to goethite only at Al/(Al+Fe)≃0.3. The capacity of the goethite structure to tolerate more Al may explain why goethite replaced magnetite at higher Al concentrations. -from Authors
