A white fluffy powder with excellent compatibility with other materials, featuring uniform particle size, large specific surface area, great dispersibility, high transparency, and strong nanomaterial efficacy. It delivers outstanding photocatalytic performance, self-cleaning/purification effects, and significantly boosts product adhesion. Widely used in coatings, ceramics, plastics, fibers (for antibacterial/deodorant functions), photocatalysts, air purifiers, solar cells, gas sensors, and lithium battery materials. Its superhydrophilicity prevents water droplet formation, enabling self-cleaning glass, tiles, and anti-fog car rearview mirrors.
