Uses & Benefits of Titanium Dioxide Ⅲ

Ultrafine-grade, or Nanoscale Titanium Dioxide

Ultrafine grades of titanium dioxide are most commonly used in the following specialty applications:  

Sunscreen: Nanoscale titanium dioxide becomes transparent to visible light while serving as an efficient UV light absorber. Because the particle size is so small, nano-titanium dioxide does not reflect visible light, but does absorb UV light, enabling a transparent barrier that protects the skin from the sun’s harmful rays. According to the Skin Cancer Foundation, using sunscreens containing titanium dioxide can help prevent the occurrence of skin cancer.

Catalysts: Nanoscale titanium dioxide is used as a support material for catalyst applications. Major uses include in the automotive industry to remove harmful exhaust gas emissions and in power stations to remove nitrous oxides.
