Synthesis of an Anticorrosive Pigment by Thermal Treatment of Iron Oxides from Steel Industry Wastes
This work reports the obtaining of an anticorrosive pigment composed mainly of hematite (ɑ-Fe2O3) from a powder steel industry waste from rust scale of rebar steel. This residue is mainly composed of Fe2O3 (87.97 %), SiO2 (6.13 %), CaO (1.88 %), Al2O3 (1.30%) and MnO (0.77 %). The total iron oxide o...

| description | This work reports the obtaining of an anticorrosive pigment composed mainly of hematite (ɑ-Fe2O3) from a powder steel industry waste from rust scale of rebar steel. This residue is mainly composed of Fe2O3 (87.97 %), SiO2 (6.13 %), CaO (1.88 %), Al2O3 (1.30%) and MnO (0.77 %). The total iron oxide of the residue is constituted by the following crystalline phases: magnetite, maghemita, lepidocrocita, wüstite, goethite and hematite. The production of a pigment with a high content of hematite was possible thanks to the high content of precursor iron oxides, which were calcined at different temperatures (750-850 °C) and holding times (0.5-1.50 h). For characterizing the iron content chemically and to identify their iron oxides phases, it was used X-ray fluorescence (XRF) and X-ray diffraction (XRD). The results showed that the pigment with the highest amount of hematite (ɑ-Fe2O3) was obtained at a calcination temperature of 850 °C and a holding time of 1.00 h. |

Este trabajo reporta la obtención de un pigmento anticorrosivo compuesto principalmente por hematita (ɑ-Fe2O3) a partir de un residuo siderúrgico en polvo proveniente de la cascarilla de óxido superficial de varillas de acero para refuerzo de concreto. Este residuo está compuesto principalmente por Fe2O3 (87.97 %), SiO2 (6.13 %), CaO (1.88 %), Al2O3 (1.30%) y MnO (0.77 %). El óxido de hierro total del residuo está constituido por las siguientes fases cristalinas: magnetita, wustita, lepidocrocita y hematita. La producción de un pigmento con alto contenido de hematita fue posible gracias al alto contenido de óxidos de hierro precursores, los cuales fueron calcinados a diferentes temperaturas (750-850 °C) y tiempos de sostenimiento (0.5-1.50 h). Para caracterizar químicamente el contenido de hierro e identificar sus fases en óxidos de hierro, se utilizaron las técnicas de fluorescencia de rayos X (XRF) y difracción de rayos X (XRD). Los resultados mostraron que el pigmento con mayor cantidad de hematita (ɑ-Fe2O3) se obtuvo a una temperatura de calcinación de 850 °C y un tiempo de sostenimiento de1.00 h.
