Titanium dioxide, aka TiO2, is a fine white powder that provides extreme whiteness to materials such as paints, plastics, papers, inks and so on. The paints containing TiO2 have high hiding power, also known as the ability to hide a substrate. Titanium dioxide can make this more effectively than any other white pigment being used in paints. Since titanium dioxide has very high opacity and whiteness, the TiO2 white pigment is the most important material used by the paints and plastics industry to add extra whiteness and opacity to the products. These unique properties of titanium dioxide are all derived from its refractive index which expresses the ability to bend and scatter light. As far as we know, titanium dioxide has the highest refractive index of any material, even diamond.
Titanium dioxide is widely used as an opacifier in glass and porcelain enamels, paints, paper, plastics, cosmetics, sunscreens and other industries. Before being used in these products, titanium dioxide needs to be mined, refined and ground to a fine, uniform particle size. One of the most important advantages that titanium dioxide has is its resistance to discoloration under UV light. Titanium dioxide is found in a form known as ilmenite which is found in the iron ore.
In conclusion, there are three major applications of titanium dioxide. First, titanium dioxide can be used as a pigment. Tio2 used to give whiteness and opacity to products such as paint, plastics, paper, inks, fibers, food and cosmetics. Second, titanium dioxide can be used as anti microbial coating. The titania in tio2 has photo catalytic property which makes the material an option for applications such as food preparation surfaces, medical devices, air conditioning purifiers and sanitary ware surfaces. Last, titanium dioxide can be used as oxygen sensors. Titanium dioxide can be used to sense the amount of oxygen present in an atmosphere which is used for studying the contents of atmosphere.
