TITANIUM DIOXIDE
UV Resistance: Titanium(IV) oxide provides effective ultraviolet radiation protection in UV-blocking textiles, skin protection formulations, and sunscreen products, delivering broad-spectrum UV attenuation.
Versatile Applications: This compound demonstrates multifunctional utility across cosmetic products, self-cleaning surface coatings, advanced ceramics, photocatalytic air purification, and water treatment systems.
Optical Transparency: The anatase crystalline polymorph exhibits superior near-UV transparency, making it particularly suitable for optical coatings and functional film applications.
Industrial Applications: In metallurgical processes, it serves as a crucial precursor for manufacturing titanium-based alloys, ferrotitanium, and metal carbide composites, supporting advanced material production for aerospace and automotive sectors.
Anatase crystals demonstrate reduced hardness and refractive index values compared to the rutile polymorph, attributable to distinct crystalline configurations. While anatase exists in a metastable state with long-term kinetic stability, it undergoes an irreversible phase transformation to rutile when heated above 700°C. This crystalline form exhibits enhanced transmittance for near-ultraviolet radiation due to its specific electronic band structure.
