【摘要】以硫酸法钛白粉生产的中间产品———水洗后的偏钛酸为原料,采用硫酸氧钛溶液中和法,成功地制得了粒度可控、分布均匀的纳米TiO2粉体。研究了相关反应条件,为进一步工业化生产打下了基础。更多还原

【Abstract】 With hydrated titanium dioxide after waterwashing,intermediate products in manufacturing process of titanium white pigment by sulphuric acid method, for the raw materials, adopting TiOSO4 solution neutralization process, nanometer powders of TiO2, whose dimension was even and can be controlled, have been successfully made. The relevant reaction conditions have been studied, which provide the foundation for further industrialization.更多还原
