titaniumdioksid

Titanium dioxide, also known as titanium(IV) oxide, is a white, opaque, and naturally occurring oxide of titanium. It has the chemical formula TiO2 and is found in various minerals, including rutile, anatase, and brookite. Titanium dioxide is widely used in various industries due to its unique properties, such as high refractive index, excellent UV absorption, and chemical inertness.

In the paint and pigment industry, titanium dioxide is a key component in white paints and coatings, providing opacity and brightness. It is also used in sunscreens and cosmetics for its UV-blocking properties. In the food industry, it is used as a food additive (E171) to provide opacity and whiteness to products like milk, ice cream, and chewing gum.

Titanium dioxide is also used in the production of titanium metal through the Kroll process. It is a catalyst in the production of sulfuric acid and is used in the manufacture of self-cleaning glass and other transparent materials. Additionally, it is used in the production of photovoltaic cells and as a pigment in plastics and ceramics.

Titanium dioxide is generally considered safe for use in various applications, but it is important to note that exposure to high concentrations of titanium dioxide dust can cause respiratory issues. Proper handling and safety measures should be followed when working with this material.
