Ultra-fine or Nano Grade Titanium Dioxide
Pure titanium dioxide is a kinds of fine white powder that provides bright white pigments. Titanium dioxide has been used a whole century in many industrial and consumer products including paints, coatings, adhesives, paper, plastics and rubber, printing inks, coated fabrics and textiles as well as ceramics, floor coverings, roofing materials, cosmetics, toothpaste, soap, water treatment chemicals, pharmaceuticals, food coloring, automotive products, sunscreens and catalysts, etc.

Pure Titanium dioxide is produced into two forms. The main form, which constitutes more than 98% of the total output, is pigment grade titanium dioxide which utilize the excellent light scattering performance of the titanium dioxide in applications that require white opacity and brightness. Another production form of titanium dioxide is ultra-fine (nanomaterials) products. This form can be selected when different properties such as transparency and maximum UV absorption are required.
    

Ultra-fine grade titanium dioxide is most commonly used for the following specialized applications:

Sunscreen: nano-grade titanium dioxide is transparent to visible light and can be used as an effective ultraviolet absorber. Due to the small particle size, nano-grade titanium dioxide does not reflect visible light, while absorbs ultraviolet light, forming a transparent barrier that protects the skin from harmful rays of the sun. According to the American Skin Cancer Foundation, using titanium dioxide-containing sunscreens can help prevent skin cancer.

Catalyst: nano-grade titanium dioxide can be used as a supporting material for catalyst applications.The main applications include the elimination of hazardous waste gases in the automotive industry and the removal of nitrous oxide from power stations.
