TITANIUM DIOXIDE CAS#1317-70-0
1. UV Resistance: Titanium(IV) oxide is widely used in UV-resistant fabrics, skin protection creams, and sunscreens, offering excellent protection against harmful UV rays.
2. Versatile Applications: It is used in a variety of products, including cosmetics, self-cleaning glass, ceramics, air purification, and sewage treatment, showcasing its versatility.
3. Optical Transparency: Anatase form of titanium(IV) oxide offers greater transparency in the near-UV range, enhancing its performance in optical applications.
4. Industrial Use: It plays a crucial role in the metallurgical industry for producing titanium alloys, ferrotitanium, and carbide alloys, contributing to diverse industrial processes.
Anatase crystals exhibit lower hardness and refractive indices than rutile due to differences in their crystal lattice structures. Despite being less thermodynamically stable, anatase remains metastable over time. However, above 700°C, it irreversibly converts to rutile. Optically, anatase has higher transparency in the near-UV range.
Titanium(IV) oxide is widely used in UV-resistant fabrics, skin creams, and cosmetics. It also serves as a photocatalyst and is essential in self-cleaning glass, ceramics, air purification, and chemical processes. In addition, it improves paper opacity and is crucial in producing titanium and alloy materials in metallurgy.
