Identification of minority compounds in natural ilmenites by X-ray absorption spectroscopy

Abstract: Natural ilmenites are used all over the world as raw materials in white pigment (TiO2) production. Besides the FeTiO3 in the raw material many other compounds are present. The chemical compounds based on the minority elements influence quality of the final product and are difficult to identify. The knowledge about chemical bonding of the minor elements enables to properly adjust chemical reactions during production processes and to improve quality of the final product. In this paper the X-ray absorption spectroscopy (XAS) identification of the chemical compounds formed by Mg, Mn and Cr in natural ilmenites originating from different places is presented.
