Data from: The effect of heat treatments on the phase composition and diffraction patterns of goethite to α-Fe2O3/γ-Fe2O3 transformation

Recovered iron hydroxides from Electro-coagulated (EC) sludge collected from the textile wastewater treatment plant and heat treated forms of iron oxides on phase composition properties and phase identification were reported. EC sludges containing iron hydroxides were examined with heat treatment at a temperature of 100, 300, 500 and 800 0C. The raw and analyzed data of the x-ray diffraction examinations of the raw iron hydroxides containing EC sludge and transformed iron oxides were reported. X- ray Diffraction (XRD) analytical techniques were used for both raw EC sludge and transformed iron oxides, hematite, characteristic determination. Iron oxide (Hematite) diffraction pattern as comparative to International Central Diffraction Data (ICDD) from heat treated at high temperature EC sludge were evaluated and confirmed. Raw and analyzed data of XRD analysis for both recovered iron hydroxides and transformed iron oxides is uploded in the data repository as PDF and XPS viewer.
