The Chinese Titanium Dioxide (TiO2) industry is currently undergoing a massive shift, moving from a focus on “quantity” to “quality.” For international procurement managers and R&D chemists, navigating the landscape of Chinese brands can be complex.<\/p>\n\n\n\n

Choosing the right grade depends entirely on the manufacturing process\u2014\u0425\u043b\u043e\u0440\u0438\u0441\u0442\u044b\u0439<\/strong> \u0438\u043b\u0438 \u0421\u0443\u043b\u044c\u0444\u0430\u0442<\/strong>\u2014and the specific finish required. This guide breaks down the characteristics, applications, and top-tier grades from China\u2019s leading manufacturers.<\/p>\n\n\n\n

\n\n\n\n

1. The Chloride Process: The High-End \u201cBlue\u201d Standard<\/h2>\n\n\n\n

The Benchmark for Performance<\/em><\/p>\n\n\n\n

The Chloride process is the cutting-edge standard in the industry (pioneered globally by companies like Chemours). In China, LB Group (Lomon Billions)<\/strong> is the absolute leader in this space, with other players like CITIC Titanium and Pangang Vanadium Titanium growing their capacity.<\/p>\n\n\n\n

Key Characteristics:<\/h3>\n\n\n\n
    \n
  • Whiteness & Undertone:<\/strong>\u00a0Produces a distinct\u00a0blue undertone<\/strong>. This makes finished products look cleaner, brighter, and visually “whiter” compared to sulfate grades.<\/li>\n\n\n\n
  • \u0427\u0438\u0441\u0442\u043e\u0442\u0430:<\/strong>\u00a0The distillation process removes heavy metals (like iron), resulting in exceptionally low impurity levels.<\/li>\n\n\n\n
  • \u0414\u0438\u0441\u043f\u0435\u0440\u0441\u0438\u044f:<\/strong>\u00a0Very narrow particle size distribution means it disperses easily in resins, requiring less energy to grind.<\/li>\n\n\n\n
  • \u0423\u0441\u0442\u043e\u0439\u0447\u0438\u0432\u043e\u0441\u0442\u044c \u043a \u043f\u043e\u0433\u043e\u0434\u043d\u044b\u043c \u0443\u0441\u043b\u043e\u0432\u0438\u044f\u043c:<\/strong>\u00a0Generally superior to sulfate grades, making it ideal for long-term outdoor exposure.<\/li>\n<\/ul>\n\n\n\n

              2. The Sulfate Process (Rutile): The Market Workhorse<\/h2>\n\n\n\n

              The Balance of Performance and Cost<\/em><\/p>\n\n\n\n

              This is the most mature technology in China. While the process is older, advanced surface treatment (coating) technologies allow these grades to perform very close to chloride grades in many applications.<\/p>\n\n\n\n

              Key Characteristics:<\/h3>\n\n\n\n
                \n

              • Undertone:<\/strong>\u00a0Slightly yellower than chloride grades (often undetectable to the naked eye but measurable by instruments).<\/li>\n<\/ul>\n\n\n\n

                \u0418\u0434\u0435\u0430\u043b\u044c\u043d\u044b\u0435 \u043e\u0431\u043b\u0430\u0441\u0442\u0438 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f:<\/h3>\n\n\n\n
                  \n
                • Architectural interior and exterior paints (used by majors like Nippon Paint\/Dulux).<\/li>\n\n\n\n
                • Industrial anti-corrosion paints.<\/li>\n\n\n\n
                • Masterbatches, pipes, and profiles.<\/li>\n\n\n\n

                            3. The Sulfate Process (Anatase): The Economic Entry<\/h2>\n\n\n\n

                            For Indoor and Special Applications<\/em><\/p>\n\n\n\n

                            In the sulfate process, if the calcination temperature is kept lower and no crystal conversion occurs, the result is Anatase TiO2.<\/p>\n\n\n\n

                            Key Characteristics:<\/h3>\n\n\n\n
                              \n
                            • Whiteness:<\/strong>\u00a0Often whiter than Rutile due to crystal structure.<\/li>\n\n\n\n

                            • The “Fatal Flaw” (Weatherability):<\/strong>\u00a0It has high photo-activity. If used outdoors, UV light will cause it to chalk (powder) rapidly.\u00a0Strictly for indoor use.<\/strong><\/li>\n\n\n\n
                            • Lower Hiding Power:<\/strong>\u00a0Lower refractive index requires a higher loading volume to cover the background color.<\/li>\n<\/ul>\n\n\n\n

                              \u0418\u0434\u0435\u0430\u043b\u044c\u043d\u044b\u0435 \u043e\u0431\u043b\u0430\u0441\u0442\u0438 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f:<\/h3>\n\n\n\n
                                \n

                                Brands usually denote these with an ‘A’<\/strong>. Differences between brands are less pronounced than in Rutile.<\/p>\n\n\n\n

                                  Technical Deep Dive: Why is there no “Chloride Anatase”?<\/h2>\n\n\n\n

                                  You might notice a pattern: Chloride grades are always<\/em> Rutile. Why?<\/p>\n\n\n\n

                                  It comes down to Thermodynamics<\/strong> \u0438 Economics<\/strong>.<\/p>\n\n\n\n

                                    \n
                                  1. Temperature Defines Structure:<\/strong>\u00a0The core of the Chloride process is the oxidation of Titanium Tetrachloride (TiCl4) at extremely high temperatures (1200\u2103 – 1500\u2103<\/strong>). At this heat, the metastable Anatase structure cannot exist; it spontaneously rearranges into the thermodynamically stable\u00a0\u0420\u0443\u0442\u0438\u043b<\/strong>\u00a0structure.<\/li>\n\n\n\n
                                  2. The Sulfate Advantage:<\/strong>\u00a0The Sulfate process finishes with a calcination step at lower temperatures (800-900\u2103). This allows manufacturers to “choose” their crystal form by adjusting heat and adding seed crystals.<\/li>\n\n\n\n
                                  3. The Economic Paradox:<\/strong>\u00a0The Chloride process is expensive and technical. Anatase is an economic product. Even if you could force the Chloride process to make Anatase (by lowering temps, which ruins efficiency), it would make no business sense to use the world’s most expensive process to make the cheapest commodity product.<\/li>\n<\/ol>\n\n\n\n
                                    \n\n\n\n

                                    \u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/strong><\/p>\n\n\n\n

                                    For “Blue-phase” whiteness and top-tier durability in automotive or high-end plastics, Chloride (LB Group BLR series)<\/strong> is the go-to. For the vast majority of architectural and industrial applications where cost and performance must balance, Sulfate Rutile (like the R-996)<\/strong> remains the smart choice.<\/p>\n\n\n\n
