摘　　要：TiO_(2)具有优异的白度、消色力等颜料性能,是物理、化学性质稳定的功能材料。综述了工业生产TiO_(2)制备方法的现状和研究进展,分析各种制备方法的优势、劣势和发展前景。硫酸法能制备锐钛型和金红石型二氧化钛,并且可以制备不同类型的功能材料产品,氯化法只能制备金红石型产品,硫酸法与氯化法将会长期共存。氯化法中的熔盐氯化技术与中国的钛资源现状更加契合,沸腾氯化法的技术瓶颈和对高钛渣原料的严苛要求是下一步中国二氧化钛行业面临的急需解决的问题。新工艺技术中盐酸法对原料的要求简单,能够生产不同晶型和性能的Ti O_(2),最具有工业化发展前景。今后,各种工业制备方法的发展方向必须向清洁、绿色、低碳和废物综合利用的方向发展,以满足日益严苛的环保要求和国内钛资源现状。TiO_(2)has excellent pigment properties such as whiteness and fading power,and it is a functional material with stable physical and chemical properties.The current status and research progress of TiO_(2)industrial production preparation methods were reviewed,the advantages,disadvantages,and development prospects of various preparation methods were analyzed.The sulfuric acid method could prepare rutile type and rutile type titanium dioxide,and different types of functional material products could be prepared.The chloride method could only prepare rutile type products,and the sulfuric acid method and chloride method would coexist for a long time.The molten salt chlorination technology in the chlorination process was more in line with the current situation of titanium resources in China.The technical bottleneck of boiling chlorination and the strict requirements for high titanium slag raw materials were the urgent problems that the Chinese titanium dioxide industry would face in the next step.The hydrochloric acid method in the new process technology had simple requirements for raw materials and could produce TiO_(2)with different crystal forms and properties,making it the most promising for industrial development.The future development direction of various industrial preparation methods must shift towards clean,green,low-carbon,and comprehensive waste utilization to meet increasingly stringent environmental requirements and the current status of domestic titanium resources.
