“…The X-ray diffraction of the ilmenite sample ( Figure 1) indicates predominantly ilmenite (JCPDS number 29-0733) and minor quantities of pseudorutile (JCPDS number 29-1494). Similar observation was also made by Sasikumar et al, [19] for the ilmenite of this area. The variation of particle size and particle size distribution is shown in Figure 2.…”

Ilmenite from the Chhatrapur coast, Odisha, India, was studied using optical microscope, X-ray diffraction, particle size analysis, and electron microprobe to decipher their micromorphology, texture(s), and elemental composition. The micromorphological features by electron microscope indicate that weathering processes such as mechanical and chemical, affected the placer heavy mineral ilmenite. These detrital ilmenites contain TiO 2 in the range of 50.25% to 55.41% and FeO 42.72% to 49.99% in addition to Al 2 O 3 , MgO, MnO, CaO, Na 2 O, Cr 2 O 3 , NiO, ZnO, ZrO 2 , V 2 O 5 , and HfO 2 (0 to 0.034%). Ti/(Ti + Fe) ratio in the ilmenite varied from 0.413 to 0.5, which indicates the effect of weathering/oxidation confirming microscopic observations. All the results revealed that these ilmenite grains were derived from the gneissic/granitic, basic and high grade metamorphic rocks, belonging to the Eastern Ghats Group of the Precambrian complex of coastal Orissa.

RESUMENEl dopaje del dióxido de titanio (TiO 2 ) con iones de metales de transición, como el Fe 3+ , es uno de los mé-todos empleados para modificar las propiedades físicas y químicas de este material. En este trabajo se analizó la influencia de la temperatura de calcinación en las propiedades texturales y estructurales del dióxido de titanio dopado con Fe 3+ , Fe(III)-TiO 2 , sintetizado a partir del mineral ilmenita mediante un proceso de extracción con ácido sulfúrico. El material sintetizado fue caracterizado por fluorescencia de rayos X, difracción de rayos X, espectroscopía infrarroja e isotermas de adsorción-desorción de nitrógeno a 77 K. El Fe(III)-TiO 2 sintetizado mostró la fase anatasa como único componente cristalino, con buena estabilidad térmica a 700 °C, revelando la sustitución isomórfica de hierro en la estructura del TiO 2 . Las distribuciones de tamaños de poros del Fe(III)-TiO 2 tratado a 400, 500, 600 y 700 °C mostraron un comportamiento monomodal con máxima población en la región de los mesoporos. El aumento de la temperatura de calcinación del Fe(III)-TiO 2 condujo a la formación de estructuras sólidas con mayores radios de poros.Palabras clave: TiO 2 , ilmenita, dióxido de titanio dopado con hierro(III), anatasa.
