Abstract
Aluminum-substituted hematite (α *-Fe2O3) with an unusual morphological structure is formed upon the aging of coprecipitated Fe(III)-Al(III) hydroxides with excess Fe(III). The crystals of this hematite are found in separate layers and includes seams of an aluminum-containing phase. In samples with excess Al(III) content, theα *-Fe2O3 crystals are found as seams in mixed aggregates of boehmite andα *-Fe2O3.
