Domestic production technology for titanium dioxide via chlorination method
Thread Content
Let’s discuss the scale and technologies used in current domestic titanium dioxide projects produced by chlorination methods (those that are already operational, under construction, or planned for construction), in more detail.
We know that the main raw material used by Panjin Titanium Industry is high-titanium slag; titanium tetrachloride is obtained through molten salt chlorination. Titanium tetrachloride is then refined using mineral oil to produce refined titanium tetrachloride, which is oxidized to yield a semi-finished product of titanium dioxide. This semi-finished product is further processed to produce the final titanium dioxide product.
Upstairs, Brother Dong is right. Additionally, as a supplementary point, I heard that Yunnan Xinli Group is planning to set up a production line for titanium dioxide produced by the chlorination method. It’s at least in the 60,000-ton class.
Yunnan Xinli Group claims to use technology from the German company TiKon; however, I am not aware of the details regarding this technology, and it is said that German technology is not very advanced.
As far as I know, there is only one manufacturer of titanium dioxide produced by the chlorination method in China. At present, Jinzhou has a production capacity of 30,000 tons, and it uses process technologies that are the result of China’s own intellectual property development. In addition, DuPont plans to establish a titanium dioxide production plant using the chlorination method in Shandong, with a large scale. There are many online resources on the production techniques for chlorination; the original poster can look them up online. This post was last edited by 521yxc521 on 2009-4-10 08:49.]
It is said that Titancon is a consulting company founded by several people who came from a German titanium dioxide manufacturer. I wonder if its technology is advanced? There are reports that the newly established project has already started construction, so there should be no technical issues. If anyone is aware of the latest developments regarding Xinli, please let me know how things are progressing. Thank you in advance! ! !

I wonder what raw materials they plan to use? I also heard that Luohe Xingmao Titanium Industry Co., Ltd. began preparing to launch a titanium dioxide production project using the chlorination method in 2004. I wonder which production technology they will use, and whether construction has already started
7# ecopluto: It’s not that easy to produce titanium dioxide using the chlorination method; the oxidation furnace, large-scale boiling chlorination furnaces, the purification of TiCl4, and its control systems are all quite challenging to manage.
It seems that the United States has recently developed a new technology for producing titanium dioxide, one that uses the hydrolysis of titanium tetrachloride. This method is shorter than the chlorination process, and it enables the production of nano-titanium dioxide, anatase-type titanium dioxide, rutile-type titanium dioxide, and titanium yellow. It is easier to handle from an environmental perspective than molten salt chlorination and boiling chlorination. Please pay more attention.
What is the minimum production capacity required for titanium dioxide produced by the chlorination method in order to proceed with a project? **Is there such a requirement?
Does anyone know any information about the German company TiCon? Thank you~
