Synthesis and characterisation of iron oxides: Effect of calcination temperature and their application as inorganic pigment

open access: yesColoration Technology, EarlyView.
Abstract This research aimed to investigate the effect of calcination temperature on the phase, morphological and optical properties of iron oxides: hematite (α‐Fe₂O₃), magnetite (Fe₃O₄) and goethite (α‐FeOOH), synthesised by co‐precipitation, aiming at their applications as pigments.
