| 摘 要： | 以粗TiC l4(98.0%)为主要原料,通过白矿物油除钒提纯处理后,采用气相氧化法制备出金红石型TiO2,并分析了粉体的相关性能。研究表明,制备的金红石型TiO2具有较高的晶型转化率(100.0%)、白度(102.08%)和消色力(123%),且粒度适宜(258 nm)、粒度分布较窄、近似球形、分散性好等优异性能。A lC l3蒸气在气相反应中起到了晶型转化剂的作用。当A lC l3加入量增加至2.6%以上时,TiO2的晶型转化率达到了最大值100.0%。

| Abstract: | The titanium tetrachloride was refined by white mineral oil using coarse titanium tetrachloride(98.0%) as raw material.The rutile titanium dioxide was produced by vapor phase oxidation of titanium tetrachloride.The research showed that reluctant titanium dioxide appeared excellent properties,such as high phase transformation rate(100.0%),high whiteness(102.08%),high tinting strength(123%),appropriate particle size(258 nm),narrow particle size distribution,spherical,well dispersed and so on.Aluminum trichlor... |
