The synthetic rutile produced from ilmenite by oxidation and fluidization acid leaching has characteristics as rutile-type titanium(IV) dioxide, with TiO2 content of 92.96%, CaO and MgO total content......
slag and pre-oxidization roasting kinetics of the leached slag [J]. The Chinese Journal of Process Engineering, 2010, 10(3): 513-521. (in Chinese) [6] GUEGUIN M. Process of producing synthetic rutile... dilute sulfuric acid for 2 h. The XRD patterns show that the product is titanium dioxide with a rutile structure. Mechanism studies show that structures of anosovite solid solution and silicate minerals......
Fabrication and characteristics of rutile TiO2 nanoparticles induced by laser ablation LIU Pei-sheng(刘培生)1,2,3,4,CAI Wei-ping(蔡伟平)2,WAN Li-xi(万里兮)3, SHI Ming-da(石明达)4, LUO Xiang-dong(罗向东) 1.... The as-prepared products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results indicate that the rutile TiO2......
A simple and novel synthetic route to prepare anatase TiO2 nanopowders from natural ilmenite via the H3PO4/NH3 processLalinda Palliyaguru,Ushan S.Kulathunga,Lakruwani I.Jayarathna,Champa D.Jayaweera... the preparation of anatase TiO2. Calcination at temperatures above 800°C converts the anatase form of TiO2 to the stable rutile phase. The removal of iron from ilmenite during the commercial production......
-quality titanium slag or synthetic rutile for the feedstock of chloride process. There are many methods developed or under development all over the world to prepare the high-quality titanium slag or synthetic rutile from ilmenite, including the electric furnace smelting process [7], the Becher process [8], the acid leaching [9] and other methods [10,11]. The electric furnace smelting process......
