|
摘要
研究了以钛冶金过程中水洗TiCl_4尾气产生的酸性吸收液为原料,通过调节溶液pH使其中的二氯氧钛水解制备二氧化钛。试验结果表明:在体系pH=6条件下,可制备出二氧化钛产品,钛回收率达79.7%,且过滤容易;产品的X射线衍射和扫描电镜表征结果表明,产品全部为金红石型,粒度在100~300nm之间;利用TiCl4尾气水洗液制备二氧化钛效果较好。
The preparation of titanium dioxide using TiCl_4 offgas absorption solution yielding in the process of titanium metallurgy by adjusting pH of the solution was studied.The results show that at solution pH =6,titanium dioxide can be prepared with productive rate of 79.7% and a shorter filtration time.The specimen was characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results show that the specimen TiO2 has rutile phase and a particle size of100-300 nm.The preparing of titanium dioxide using TiCl_4 offgas absorption solution by the method is viable.
