Formula: TiO₂ 99.6
Form: Powder
Material: Titanium Dioxide
CAS Number: 13463-67-7
Commodity: Compounds
Max Particle Size:
45μm
Titanium Dioxide Powder is a high-refractive-index ceramic material with outstanding chemical stability, UV resistance, and photocatalytic activity. Available in anatase and rutile forms, TiO₂ powder is widely used for optical, catalytic, and electronic applications. Industries including pigments and coatings, environmental remediation, and energy harvesting use TiO₂ powder for high-performance paints, photocatalytic degradation of pollutants, and dye-sensitized solar cells. Specific uses include UV-blocking coatings, self-cleaning surfaces, and photoelectrodes in solar devices. In research, TiO₂ powder supports studies on photocatalysis mechanisms, bandgap engineering, and nanostructured surface optimization for enhanced light absorption. Its combination of optical efficiency, chemical inertness, and catalytic potential makes it a cornerstone material for sustainable technologies and high-performance functional surfaces.
