What is a Titanium oxide (TiO₂)?

Titanium oxide (TiO₂) is an inorganic compound composed of titanium (Ti) and oxygen (O), with the chemical formula TiO₂. It occurs naturally in minerals such as rutile, anatase, and brookite. Titanium oxide is a white, crystalline powder that is widely used for its durability, stability, and UV absorption capabilities. Titanium oxide is primarily used as a white pigment in paints, cosmetics, foods, and pharmaceuticals. Its excellent opacity and whiteness make it essential for automotive, building materials, and consumer products, where it provides long-lasting weather resistance.

Due to its ability to efficiently absorb UV rays, titanium oxide is widely used in sunscreens and cosmetics to block UV radiation, protecting the skin from harmful effects like skin cancer. Additionally, it is recognized for its environmental benefits as a photocatalyst, helping to purify air and water. Titanium oxide photocatalysis is highly effective in breaking down pollutants, making it a promising solution in environmental protection. Moreover, its biocompatibility makes titanium oxide valuable in medical applications, particularly in implants and dental prosthetics. As a result, titanium oxide plays a critical role across various industries, with expanding applications anticipated in the future.
