Overview of Fumed Titanium Dioxide Powder
Fumed Titanium Dioxide is an excellent white powder with hydrophilic groups on the surface, and the product does not have any pigment characteristics. The average particle size of the primary particle is about 21nm. The particle size and the density of 4g/cm3 give it a unique surface of 50m2/g.
Hydrophilic Fumed Titanium Dioxide TiO2 Powder
Fumed titanium dioxide belongs to the mixed crystal type. The weight ratio of anatase to rutile is about 80: 20. Due to the mixing of the two structures, the defect density in the TiO2 lattice is increased, the carrier concentration is increased, and the number of electrons and holes is increased, which makes it have a more vital ability to capture the solution components (H2O, oxygen, organic matter) on the surface of TiO2.
Nano titanium dioxide has excellent properties such as ultraviolet absorption, photocatalytic sterilization, and decomposition of organic pollutants. It can be used in nano-coatings, air purifiers, self-cleaning glass, ceramics, and so on.
Nano titanium dioxide is widely used in the fields of antibacterial and anti-mildew, exhaust purification, deodorization, water treatment, weather resistance and anti-aging, automobile topcoat, and so on. It is widely used in the fields of environment, information, materials, energy, medical treatment, and health.

FAQs of Fumed Titanium Dioxide Powder:
Q: What are the main applications of fumed titanium dioxide powder?
A: As a white pigment, providing excellent covering power and color strength, while improving the weatherability and UV resistance of the coating. Used as a filler or reinforcing agent to improve the mechanical strength, abrasion resistance and thermal stability of plastic products. Due to its mild safety and good light transmission, it is often added to sunscreen, foundation and other products to provide physical sun protection.
Q: What should be noted when using fumed titanium dioxide powder to ensure the best results?
A: Select the most suitable product according to the specific application scenario and technical requirements (such as particle size, specific surface area, crystal morphology, etc.). Add in strict accordance with the proportion of the formula; too much may lead to agglomeration or affect the function of other ingredients; too little will not achieve the desired effect. Ensure adequate mixing and uniform distribution throughout the mixing and molding process to avoid excessive local concentration or uneven dispersion.
Q: What are the potential environmental and health effects of fumed titanium dioxide powders? What safety measures should be taken when using?
A: In general, moderate use will not cause significant harm to the environment, but a large number of emissions may cause dust pollution, affecting air quality. In addition, if it enters the water body, it may have some impact on aquatic organisms. Long-term inhalation of high concentrations of titanium dioxide dust may irritate the respiratory tract and lead to respiratory diseases. Skin contact or eye splashes may also cause discomfort. Wear suitable masks, gloves and goggles to minimize direct contact.
Q: How to choose the fumed titanium dioxide powder type and supplier for a specific project?
A: First determine the specific use scenario and technical parameters, such as the required particle size range, specific surface area, crystal type, etc. Examine the supplier's historical performance, customer reviews and level of technical support, prioritizing those with extensive experience and a good reputation. Request samples from potential suppliers and conduct comprehensive tests under laboratory conditions, including physicochemical properties, processing suitability and final product performance. Consider the market price of the product, volume discount policy and after-sales service quality to find the most cost-effective partner.
