We can offer nm-TiO2 in anatase and rutile crystallographic phases. It appears in white powder, with a high purity and fine particle diameter. nm-TiO2 (anatase) has a good light catalytic activity and can be widely used for sewage disposal, air purification, catalysts and so on. nm-TiO2 (rutile) plays a good role of shielding ultraviolet rays. It can be widely used for sunscreen cosmetics, functional chemical fibers, high-grade plastics and other fields.
