Relying on continuous innovation in the application technology of rare earth fine chemicals, high-cerium sulfuric acid has achieved large-scale application and promotion in the industrial production of high-end titanium white powder. As an important four-valent cerium-based rare earth fine chemical, high-cerium sulfuric acid, with its excellent oxidation activity, coating modification ability and process adaptability, can effectively make up for the industry shortcomings such as weak weather resistance, easy yellowing and light activity of traditional titanium white powder, and vigorously promote the transformation and upgrading of the titanium white powder industry towards high-end, high stability, green and low-carbon directions. It is an important achievement of rare earth new materials empowering the fine chemical industry to improve quality and increase efficiency. 、
Titanium dioxide is a core industrial white inorganic pigment, widely used in coatings, plastics, papermaking, high-end building materials, automotive manufacturing, etc., and is a key basic chemical material supporting the development of the national economy. With the continuous upgrading of quality standards in downstream industries such as high-end painting, outdoor engineering, and automotive paint, the market has continuously raised requirements for core properties of titanium dioxide, such as light stability, weather resistance, anti-aging, and uniform dispersion. Traditional process products have become difficult to meet the application needs of high-end scenarios. The industry urgently needs new modified materials and technologies to achieve product iteration and upgrading.
Sulfuric acid high cerium is highly stable and has excellent oxidation selectivity, and is a core special additive for titanium dioxide salt treatment and surface modification processes. By adding sulfuric acid high cerium in the production process and undergoing high-temperature calcination, it can generate cerium dioxide active components, precisely the light-active sites on the surface of titanium dioxide crystals， effectively inhibiting photocatalytic oxidation reactions from the source， and effectively solving problems such as yellowing， powdering， and aging of the product during long-term use， significantly improving the stability and service life of titanium dioxide products.
Compared with traditional modification processes， the industrialization advantages of sulfuric acid high cerium modification technology are significant. By precisely regulating process parameters， a uniform and dense cerium dioxide protective layer can be formed on the surface of titanium dioxide particles. Official tests show that after modification， the weather resistance of rutile-type titanium dioxide is improved by more than three times， and the anti-ultraviolet aging ability is significantly enhanced， which can meet the strict usage requirements of high-end outdoor coatings， original factory paint for automobiles， and ship anti-corrosion， etc. This technology can be compatible with mainstream production lines of sulfuric acid and chlorination methods， does not require large-scale equipment renovation， has both process feasibility and industrial economic benefits， and is suitable for large-scale production.
In terms of green production， sulfuric acid high cerium can effectively assist the titanium dioxide industry in a low-carbon transformation. This material has a high reaction conversion rate， low residue， and can be recycled， which can optimize the production process， reduce energy consumption and waste emissions， replace traditional inefficient modification additives， reduce auxiliary material consumption， and improve product yield rate， helping enterprises reduce costs， increase efficiency， and produce in a green and compliant manner， and aligning with the high-quality green development orientation of the chemical industry.
Currently， China’s rare earth industry is accelerating its transformation towards high-end functional material application fields. The deep application of sulfuric acid high cerium in the titanium dioxide industry effectively the integration channel of rare earth new materials and the basic chemical industry， extends the rare earth deep processing industry chain， enhances the value of rare earth products， breaks through the key process barriers of high-end modified titanium dioxide， and further consolidates the independent control foundation of China’s fine chemicals and high-end pigment industry supply chain.
