Titanium dioxide, also known as titanium(IV) oxide or titania, is a white, crystalline solid with the chemical formula TiO2. It is a naturally occurring mineral that is commonly found in various types of rocks and soils.
Titanium dioxide is widely used in many industries due to its unique properties. It is a highly effective and stable white pigment, making it a popular choice for use in paints, coatings, plastics, and paper. Its high refractive index also gives it excellent UV-blocking properties, making it a common ingredient in sunscreens and other skincare products.
In addition to its use as a pigment, titanium dioxide is also a versatile catalyst. It is often used in the production of various chemicals, such as fertilizers, plastics, and pharmaceuticals. Its photocatalytic properties make it useful in environmental applications, such as air and water purification.
