| 1 | Decomposition of acid dissolved titanium slag from Australia by sodium hydroxide显示文摘The kinetics of the decomposition of acid dissolved titanium slag with a sodium hydroxide system under atmospheric pressure was studied. The effect of reaction temperature, particle size and NaOH-to-slag mass ratio on titanium extraction was investigated. The results show that temperature and particle size have significant influence on titanium extraction. The experimental data of titanium extraction show that the shrinking core model with chemical reaction controlled process is most applicable for the decomposition of slag, with an apparent activation energy of 62.4 kJ·mol-1. Approximately 85 wt.%-90 wt.% of the titanium can be extracted from the slag under the optimal conditions. In addition, the purity of titanium dioxide obtained in the product is up to 98.5 wt.%. | FENG Yang WANG Jinggang WANG Lina QI Tao XUE Tianyan CHU Jinglong | 2009 | Rare Metals2009，28，6： | 5 |
| 2 | Removal of iron from ilmenite by KOH leaching-oxalate leaching method显示文摘Oxalic acid was used for the removal of iron from the intermediates of ilmenite leached by KOH liquor. Various parameters, such as pH, temperature, initial oxalate concentration, and illumination were investigated. Meanwhile, it was found that orthorhombic crystal Ti2O2(OH)2(C2O4)·H2O formed as the leaching proceeded. Scanning electronic microscope (SEM) images implied that the formation of Ti2O2(OH)2(C2O4)·H2O with good crystallinity proceeded through three stages. Calcining Ti2O2(OH)2(C2O4)·H2O, anatase (350°C) or rutile (550°C) type TiO2 was obtained, respectively. Element analysis found that the calcined product contained 94.9% TiO2 and 2.5% iron oxide, but only about 1600 ppm dissolvable iron oxide was left, which indicates that oxalic acid was comparatively effective on iron oxide removal from the intermediates. Finally, an improved route was proposed for the upgrading of ilmenite into rutile. | WANG Yuanbo QI Tao CHU Jinglong ZHAO Wei | 2010 | Rare Metals2010，29，1： | 5 |
| 3 | Study on Lithium Insertion in Lepidocrocite and ,λ-MnO2 Type TiO2: A First-Principles Prediction显示文摘TiO2 是为可充电的锂电池的潜伏的阳极材料。我们的模拟当模特儿,基于纤铁矿和 -MnO2 类型 TiO2,被密度调查功能的理论(DFT ) 。关键问题集中于锂插入地点,电子结构,和 Li+ 离子的进行的路径。我们的计算数据显示 -MnO2 类型 TiO2 的计算电压比纤铁矿类型 TiO2 的高。纤铁矿类型 TiO2 沿着的 Li+ 离子迁居精力障碍[1 0 0 ] 方向(0.45 eV ) 比的低沿着[1 1 0 ] 方向(0.57 eV ) 。-MnO2 的精力障碍打 TiO2 在邻近的嵌入的地点(16c 或 8a 地点) 之中移动一个 Li+ 离子是 0.68 eV。 | Yahui Liu Jingyi Wu Wei Zhao Jinglong Chu Tao Qi | 2013 | Chinese Journal of Chemistry2013，31，10： | 2 |
| 4 | Production of TiO_2 from CaTiO_3 by alkaline roasting method显示文摘CaTiO3 was decomposed by alkaline roasting method for the production of TiO2.The process included alkaline roasting, water leaching and acid leaching steps.In the alkaline roasting step, the factors such as roasting temperature and NaOH/CaTiO3 molar ratio were investigated and 99.5% TiO2 could be extracted from CaTiO3.In addition, it is believed that only ion-exchange between Ca2+ and Na+ takes place, while the structure of TiO 32-in CaTiO3 was not destroyed during the roasting process.In the acid leaching step, Ca(OH)2 could be completely leached at pH = 6-7 and Na2TiO3 was completely hydrolyzed simultaneously.The crystal structure of the leached sample seemed to be affected by pH and sequent calcination temperature.Finally, a flowsheet was proposed for the extraction of TiO2 from perovskite. | WANG Yuanbo QI Tao CHU Jinglong ZHAO Wei | 2010 | Rare Metals2010，29，2： | 2 |
