titánoxid

Titanoxid, also known as titanium dioxide, is a naturally occurring oxide of titanium. It is found in minerals like rutile and ilmenite. In its pure form, titanoxid is a white, powdery solid. It is one of the most widely used pigments in the world due to its exceptional brightness, opacity, and UV resistance.

The primary applications of titanoxid are as a white pigment in paints, coatings, plastics, paper, inks, and even food products. Its ability to scatter light effectively makes it an excellent whitener and opacifier. In cosmetics and sunscreens, titanoxid acts as a physical UV filter, protecting the skin from harmful ultraviolet radiation by reflecting and scattering the light.

Titanoxid exists in several crystalline forms, with the most common being anatase, rutile, and brookite. Rutile is the most stable and widely used form for pigment applications. Anatase is often used in photocatalysis due to its higher surface area.

Beyond its pigmentary and UV-blocking properties, titanoxid has also found applications in advanced technologies. Its photocatalytic activity allows it to break down organic pollutants and has been explored for self-cleaning surfaces and air purification systems. It is generally considered safe for use in its various applications, with regulatory bodies setting guidelines for its incorporation into consumer products.
